cc/gcc: do not print 'core' or 'final'

In gcc-'s core and final passes, do not print 'core' or 'final' in
log messages. We already print it in step messages.

Also, as we use the core backend to build the bare-metal final gcc,
it can be disturbing to read 'core' while we're in fact in 'final'.

     2 On mips target, binutils currently sets DT_MIPS_RLD_MAP to 0 in dynamic

     3 section if a --version-script sets _RLD_MAP to local. This is apparently

     4 a binutils bug, but libc shouldn't segfault in this case.
