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   I'm still working on the solaris port an I have the same issue here.

     4   While trying to build the i686-nptl-linux-gnu toolchain under

     5   OpenSolaris, the problems appears during the make install rule of the

     6   libc function.

     7 

     8   The problem is that solaris tries to execute ld-linux.so.2, which is an

     9   elf 32 bits dyn lib, and it fails with a memory fault, not a "cannot

    10   execute binary file". Hence the build stops on this error.

    14   After digging a little, the problem comes from the

    15   glibc-2.6.1/posix/Makefile. It has been solved starting from glibc 2.7

    16   so I extracted a patch for glibc 2.6.1.
