Rainer Orth - Aug. 8, 2011, 12:30 p.m.
While preparing the patch to move gthr* to toplevel libgcc, I noticed
that we still have half-hearted support for the posix95 thread model.
No port uses it as the default, and the posix95 subdir in libgomp/config
isn't referenced anywhere and cannot be used.  Thus, I propose to remove
this model completely.

Bootstrapped on i386-pc-solaris2.11 to make sure there are no syntax
errors.

Ok for mainline?

Thanks.
	Rainer
