The SPARC/Linux port is very similar to the SPARC/Solaris port nowadays so it 
makes sense to copy the setting of the support for atomic primitives.

This fixes the single regression in the gnat.dg testsuite:
FAIL: gnat.dg/prot7.adb (test for excess errors)

Tested on SPARC64/Linux, applied on the mainline.

	* libgnat/system-linux-sparc.ads (Support_Atomic_Primitives): New
	constant set to True.
