[massive] add support for alternative C libraries (currently only glibc/eglibc)

other (related) changes:
 - kernel headers are now installed using "make headers_install" on 2.6
 - target names now contain an openwrt "vendor" tag (e.g. mips-openwrt-linux-gnu)
 - build directory names now contain gcc/libc name/version
 - default cpu for x86 is now i486 (required to build glibc/eglibc)

+       '/etc/nsswitch.conf' configuration file to decide how to handle

+
+       EGLIBC_NSSWITCH_FIXED_CONFIG

+          EGLIBC build process parses this file just as EGLIBC would
+          at run time if EGLIBC_NSSWITCH were enabled, and
+          produces a C library that uses the nsswitch service
+          libraries to search for database entries as this file
+          specifies, instead of consulting '/etc/nsswitch.conf' at run
+          time.
+
+          This should be an absolute filename.  The EGLIBC build
+          process may use it from several different working
+          directories.  It may include references to Makefile
+          variables like 'common-objpfx' (the top of the build tree,
+          with a trailing slash), or '..' (the top of the source tree,
+          with a trailing slash).

+          The EGLIBC source tree includes a sample configuration file
+          named 'nss/fixed-nsswitch.conf'; for simple configurations,
+          you will probably want to delete references to databases not
+          needed on your system.
+
+       EGLIBC_NSSWITCH_FIXED_FUNCTIONS
+
+          The EGLIBC build process uses this file to decide which
+          functions to make available from which service libraries.
+          The file 'nss/fixed-nsswitch.functions' serves as a sample
+          configuration file for this setting, and explains its syntax
+          and meaning in more detail.
+
+          This should be an absolute file name.  The EGLIBC build
+          process may use it from several different working
+          directories.  It may include references to Makefile
+          variables like 'common-objpfx' (the top of the build tree,
+          with a trailing slash), or '..' (the top of the source tree,
+          with a trailing slash).
+
+          Be sure to mention each function in each service you wish to
+          use.  If you do not mention a service's function here, the
+          EGLIBC database access functions will not find it, even if
+          it is listed in the EGLIBC_NSSWITCH_FIXED_CONFIG
+          file.
+
+       In this arrangement, EGLIBC will not use the 'dlopen' and
+       'dlsym' functions to find database access functions.  Instead,
+       libc hard-codes references to the service libraries' database
+       access functions.  You must explicitly link your program
+       against the name service libraries (those whose names start
+       with 'libnss_', in the sysroot's '/lib' directory) whose
+       functions you intend to use.  This arrangement helps
+       system-wide static analysis tools decide which functions a
+       system actually uses.
+
+       Note that some nsswitch service libraries require other option
+       groups to be enabled; for example, the EGLIBC_INET
+       option group must be enabled to use the 'libnss_dns.so.2'
+       service library, which uses the Domain Name System network
+       protocol to answer queries.

+        some of these functions; you will not be able to link or run
+        C++ programs if you disable this option group.
+
+        This option group also affects the behavior of the following

+
+        These functions all take an OPENTYPE parameter which may
+        contain a string of the form ",ccs=CHARSET", indicating that
+        the underlying file uses the character set named CHARSET.
+        This produces a wide-oriented stream, which is only useful
+        when the functions included in this option group are present.
+        If the user attempts to open a file specifying a character set
+        in the OPENTYPE parameter, and EGLIBC was built with this
+        option group disabled, the function returns NULL, and sets
+        errno to EINVAL.

+Fixes a MIPS build problem (unrelated to NPTL)
+
+Message-ID: <428E8B24.1000201@realitydiluted.com>
+Date: Fri, 20 May 2005 20:13:08 -0500
+From: "Steven J dot  Hill" <sjhill at realitydiluted dot com>
+To:  crossgcc at sources dot redhat dot com,  toolchain at gentoo dot org, 
+ Shay_Gal-On at pmc-sierra dot com,  TheNop at gmx dot net
+Subject: New NPTL patches for crosstools and MIPS NPTL patches....
+
+Greetings.
+
+I have uploaded the latest NPTL patch for crosstool-0.34. I have also
+uploaded a tarball of the patches necessary to build a MIPS NPTL
+cross toolchain. To build a MIPS NPTL toolchain you will need the
+released version of binutils-2.16 and the absolute latest GCC and
+glibc code from the HEAD of cvs. Use the 'demo-mips-nptl.sh' script
+to build the toolchain. Please report bugs or issues to the crossgcc
+mailing list. Here is the link off of my FTP site:
+
+    ftp://ftp.realitydiluted.com/crosstools/crosstool-0.34/
+
+[Note: BOOTSTRAP_GCC is set by crosstool.sh when invoking make install-headers]
