I have committed the attached patch to remove checks for obsolete NetBSD
releases from the 1990s that do not support pthreads.

Bootstrapped and tested on i386-unknown-netbsdelf6.1 and
x86_64-unknown-netbsd6.1.

 	* config.gcc (*-*-netbsd*): Remove check for NetBSD versions not
 	supporting pthreds.
 	* config/netbsd.h (NETBSD_LIBGCC_SPEC): Always enable pthreads.
