    Fix typo in sol2.h
    
    I noticed that gcc/config/sol2.h uses USE_GNU_LD as a guard in one
    place only.  This is a cross of USE_GLD and HAVE_GNU_LD which doesn't
    exist so the gld variant is never used.
    
    This went unnoticed since the wrong versions of LD_WHOLE_ARCHIVE_OPTION
    and LD_NO_WHOLE_ARCHIVE_OPTION are only ever used in LIBASAN_EARLY_SPEC
    and only effective when -static-libasan is used.  gld would only warn
    about the unsupported -z options here.
    
    The issue wasn't noticed before since the only testcase using
    -static-libasan isn't run on Solaris, which this patch also corrects.
    
    Bootstrapped without regressions on i386-pc-solaris2.11 and
    sparc-sun-solaris2.11 (both as/ld and gas/gld).

            gcc:
            * config/sol2.h: Check USE_GLD instead of USE_GNU_LD.
    
            gcc/testsuite:
            * c-c++-common/asan/pr59063-2.c: Enable on Solaris.
