haiku/build/scripts/build_cross_tools_gcc4
Oliver Tappe 11ae3c5fe7 Cleanup build system and configuration.
* Drop unused variables from build system that refer to the system
  libraries.
* Drop unused lists of libgcc objects.
* Drop no longer used variables from configuration script.
* Remove no longer needed building of kernel-libgcc and -libsupc++ from
  build_cross_tools_gcc4, only the boot-specific (32-bit) libs are
  built for a x86_64 target.
* Explicitly disable threads and TLS support when building the cross
  compiler, as the only libraries that are used by Haiku's build system
  is the 32-bit libgcc and libsupc++ for the bootloader on x86_64 (and
  for that neither is wanted).
