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.

      The default is "${CT_TOP_DIR}/targets", and leaving this option

      You should not need to change that, except in one very peculiar
yann@610
    34
      setup:
yann@610
    35
       - your crosstool-NG source directory is on the network
yann@610
    36
       - you configured crosstool-NG with --local
yann@610
    37
      This kind of setup is a pain, as any action involving source file
yann@610
    38
      access would have to go through the wire. In this case, you should
yann@610
    39
      set CT_WORK_DIR to point to a path local to your machine, to avoid
yann@610
    40
      any network overhead.
yann@610
    41
      
yann@610
    42
      Do *NOT* change it if you don't know better.
