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'.

     1 ldso/mips: workaround for missing TLS macros in elfinterpret.c

     2 

     3 These macros declarations are missing, so gcc believes the code is calling

     4 a function, so any later linking will fail.

     5 

     6 Work this around by copying the mcaros from:

     7    libpthread/nptl/sysdeps/mips/dl-tls.h

     8 

     9 We can't include the header because of incompatible symbol declarations,

    10 so we just copy the macros for now.

    11 

    12 ---->  THIS IS A DIRTY HACK!  <----
