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'.

     3 	* sysdeps/unix/sysv/linux/alpha/ioperm.c: force the architecture

     4 	  to ev6 in assembly code.

    13 Hrm. gcc puts .arch ev4 into the .s, and this overrides -mev6 for as.

    14 I cannot really think of anything better than
