Subject: [PATCH] Put in a check for visibility attribute support so we don't
 add the visibility linker option when there is no visibility attribute
 support thus no visible external variables.  This is to get around a Sun
 Studio compiler version that doesn't recognize the visibility attribute but
 recognizes the -xldscope option.

This commit was SVN r20902.
