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.

     1 GCC trunk now has multiple internal headers directories, one

     2 containing the self-contained GCC-provided headers and one containing

     3 the <limits.h> (not self-contained but including libc's <limits.h> or

     4 a fixed version thereof) and the fixed headers; more such directories

     5 may be added in future.

     6 

     7 When glibc uses -nostdinc, it needs to use -isystem options for all

     8 these internal directories.  This patch teaches it about the

     9 include-fixed directory (and is harmless with old GCC versions without

    10 that directory).

    14 	* configure.in: Also pass -isystem option for GCC's include-fixed

    15 	directory.

    16 	* configure: Regenerate.
