    Enable support for atomic primitives on SPARC/Linux
    
    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)

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