Hi!
All the gcc targets for RTEMS include gcc/config/rtems.h in tm_file to add
specific linker options using LIB_SPEC.
This patch simply intends to add the same to the x86_64 target.
There are no tests in this patch because I don't see any tests for any of the
other RTEMS targets - let me know if you'd be interested in a patch for that,
and I can look into adding general tests for all the RTEMS targets or just
specific ones that _must_ support these switches - Joel and Sebastian may be
able to shed light on which it should be, if any.
P.S. - I've also added this patch to rtems-source-builder and built gcc to
verify that it works (in that the new switches do not throw "unrecognized
command line option" errors anymore, at least). Let me know if you'd like a
patch to test with rtems-source-builder, if that makes it easier for you to
verify.
Thanks!
