uClibc++: Update to 0.2.5

Switched to xz archives for smaller size.

Removed upstreamed patches.

Reorganized Makefile a little bit for clarity. Build/Prepare is not useful
anymore. Upstream converted the file to LF.

Refreshed config.

Removed -ansi option from the original CFLAGS as this was causing long
long support to be missing.

Removed fPIC. We have the macro $(FPIC) already used. No point in setting
fpic and fPIC together.

Removed pedantic -Wlong-long warnings as they are not useful.

Removed -std=gnu++98. Not only is it unnecessary (it compiles against all
standards), it actually results in a size increase. 75843 vs. 75222 (gcc
in OpenWrt defaults to g++14).

Added --gc-sections to linker flags to reduce size: 72653 vs 75222.

Removed warn linker options. They have been upstreamed.

Tested on Archer C7v2 and GnuBee PC1.

-Subject: [PATCH] Fix throw statement causing memory corruption
-
-The __cxxabiv1::__cxa_throw in the GCC's libsupc++ expects
-sizeof(__cxa_refcounted_exception) bytes be allocated before
-exception object.
-uClibc++ allocates only sizeof(__cxa_exception) before an
-exception object.
-The __cxxabiv1::__cxa_throw writes in memory before allocated:
-// gcc-5.2.0/libstdc++-v3/libsupc++/eh_throw.cc:69
-__cxa_refcounted_exception *header
-  = __get_refcounted_exception_header_from_obj (obj);
-header->referenceCount = 1;

-Subject: [PATCH] Bugfix erase() on derived __base_associative
-
-When calling erase() on a containers derived from __base_associative
-(e.g. multimap) and providing a pair of iterators a segfault will
-occur.
-
-Example code to reproduce:
-
-	typedef std::multimap<int, int> testmap;
-	testmap t;
-	t.insert(std::pair<int, int>(1, 1));
-	t.insert(std::pair<int, int>(2, 1));
-	t.insert(std::pair<int, int>(3, 1));
-	t.erase(t.begin(), t.end());
