Log message:
	Fixes to pthread-based threading on Solaris.  Quick summary:
	- Make sure we use the /usr/lib/lwp versions of the thread libraries.
	These work properly with the signal-based (same as LINUXLIBC6) mechanism for
	stopping threads.
	- Delete the old support for stopping Solaris threads using thr_suspend.
	- Remove now no-longer needed caching of sp around blocking pthread calls
	(LWP threads are capable of receiving signals while blocked on a mutex).
	- Fix config files to compile and link to the proper libraries.
	- Fix config files to ensure that things like Cerrno.c get compiled for
	thread-safe execution.
