Patch from Teemu Torma to fix Solaris 2.6 EH failures.
* gthr.h: Changed the comment about return values.
* gthr-solaris.h (__gthread_once): Do not use errno; return the
error number instead of -1.
(__gthread_key_create): Any non-zero return value is an error.
* libgcc2.c (eh_context_initialize): Check for non-zero return
value from __gthread_once.
Check that the value of get_eh_context was really changed.
