 With the patch posted previously, the build completes.  My build is
 proceeding with the other dependencies leading up to the package that
 required libatomic in the first place.  Then we'll see if it works.
 
 The build host is a SPARCstation5-110.  When it was attempting to build
 with "-mcpu=v9", a lot of atomic-related tests passed.  Now that there
 is no "-mcpu=foo" directive at all most of these previously-passing
 tests now fail.  The GCC manual page indicates that the default
 code-generation target (w/o any "-mcpu=foo") is SPARCv7.  This would
 seem appropriate for my use case as I have some SUN4C machines (IPX,
 SS1+, SS2) that I believe are generally SPARCv7 CPUs.
