libgcc: Update 'gthr-mcf.h' to include a dedicated header for libobjc
'libobjc/thr.c' includes 'gthr.h'. While all the other gthread headers
have `#ifdef _LIBOBJC` checks, and provide a different set of inline
functions, I think having one header provide two completely unrelated
set of APIs is unsatisfactory, complicates maintenance, and hinders
further development.
This commit references a new header for libobjc, and adds a copyright
notice, as in other headers.
libgcc/ChangeLog:
* config/i386/gthr-mcf.h: Include 'gthr_libobjc.h' when building
libobjc, instead of 'gthr.h'
