libc/newlib: build in the 'start files' pass

A few facts:
- building the C library requires a proper core compiler
- core compiler is issued from one of the core passes
- the C library is required to build libstdc++
- newlib is only built for baremetal
- in bare metal, the final compiler is issued from one of the core passes

So we need to build the C library between core pass 1 and core pass 2.
The only place is eithe libc_headers() or libc_start_files(). The most
pertinent seems to be libc_start_files().

So we build newlib from libc_start_files(), and leave libc() empty.

     5 where the assembler but doesn't understand the --version flag.

     8 checking whether ld is GNU ld... no

     9 checking for /usr/libexec/gcc/darwin/ppc/as... /usr/libexec/gcc/darwin/ppc/as

    10 checking version of /usr/libexec/gcc/darwin/ppc/as...
