SPARC only:

* After GCC build copy gcc/gcc/config/vxworks-dummy.h to plugin/include/config/

  cp gcc/gcc/config/vxworks-dummy.h /sparc-solaris2.10/lib/gcc/sparc-solaris2.10/4.7.3/plugin/include/config/

* gcc/Makefile.in (4.5.1) or libgcc/Makefile.in (4.7.3) needs to be changed
  to use -gstabs in LIBGCC2_DEBUG_CFLAGS instead of -g because of a bug in
  gas. Setting this variable on the make command like does not work.
