cc/gcc: add option to compile against static libstdc++, for gcc-4.4 and newer
Idea and know-how taken from CodeSourcery build script. Normal build: $ ldd arm-unknown-linux-uclibcgnueabi-gcc linux-gate.so.1 => (0xb77f3000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb76e8000) libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb75a1000) libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb757a000) /lib/ld-linux.so.2 (0xb77f4000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb755c000) CC_STATIC_LIBSTDCXX=y: $ ldd arm-unknown-linux-uclibcgnueabi-gcc linux-gate.so.1 => (0xb7843000) libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb76e6000) /lib/ld-linux.so.2 (0xb7844000) I made CC_STATIC_LIBSTDCXX default=y since I think it is always desirable.

+ Newer gcc versions use the PPL library which is C++ code. Statically
+ linking libstdc++ increases the likeliness that the gcc binary will
+ run on machines other than the one which it was built on, without
+ having to worry about distributing the matching version of libstdc++
