re PR libstdc++/38092 (libstdc++ doesn't build with GNU ld 2.19 and Sun as: no .symver support)
PR libstdc++/38092
* acinclude.m4 (HAVE_AS_SYMVER_DIRECTIVE): New test.
* src/compatibility.cc: Don't use .symver directives if
_GLIBCXX_HAVE_AS_SYMVER_DIRECTIVE is not defined.
* config.h.in: Regenerated.
* configure: Likewise.
