diff: mgnuc fixes for SunOS pthread.h -ansi problem

[Fergus Henderson]

Estimated hours taken: 0.5

scripts/mgnuc.in:
	Re-enable the passing of `-ansi' to gcc, unless `--no-ansi' is
	specified.  I think Tom Conway's change to disable it in all cases
	was committed accidentally.

	Change the code which disables `-ansi' if `--thread-safe' is
	specified and it's a sparc (since the Solaris "pthread.h"
	doesn't work with -ansi) to check the OS (Solaris or SunOS)
	rather than the architecture (sparc).
