cc/gcc: do not use the core pass-2 to build the baremetal compiler

In case we build a baremetal compiler, use the standard passes:
- core_cc is used to build the C library;
- as such, it is meant to run on build, not host;
- the final compiler is meant to run on host;

As the current final compiler step can not build a baremetal compiler,
call the core backend from the final step.

NB: Currently, newlib is built during the start_files pass, so we have
to have a core compiler by then... Once we can build the baremetal
compiler from the final cc step, then we can move the newlib build to
the proper step, and then get rid of the core pass-1 static compiler...

     3 -= BEGIN original header =-
     4 older verisons of glibc would build dl-sysdep as shared-only and dl-support as
     5 static-only.  alpha hooks in a cache variable via dl-auxv.h.  newer versions of
     6 glibc build dl-sysdep as both shared and static which means we now have symbol
     7 duplication for static builds with dl-sysdep and dl-support.  since dl-sysdep
     8 is both shared/static, there is no point in hooking dl-support anymore, so we
     9 can punt it.
