toolchain/uClibc: Disable mips16 for uClibc for now
For now, build uclibc without -mips16. There's no mips16 syscall
support AFAIK and uclibc uses inline assembly syscalls a lot.
In addition, touching errno means touching a TLS model symbol, and
that's not supported in gcc 4.6.
The __set_errno macro can be put back to calling
errno_location(). This allows much of the library to be built in
mips16 mode. I don't understand the implications to the thread library
of doing this.
A list of "build as -mno-mips16" C source files can be placed in the
mips architecture-dependent build files. Maintaining the list would be
no fun.
