re PR c++/15428 (vtables shouldn't always be weak on Darwin)
PR c++/15428
* default.h (TARGET_WEAK_NOT_IN_ARCHIVE_TOC): New name
for TARGET_EXPLICIT_INSTANTIATIONS_ONE_ONLY, with reversed sense.
* config/darwin.h (TARGET_WEAK_NOT_IN_ARCHIVE_TOC): Likewise.
* doc/tm.texi (TARGET_WEAK_NOT_IN_ARCHIVE_TOC): Rewrite
documentation to reflect the new macro name and to clarify its
meaning.
* cp/decl2.c (maybe_emit_vtables): If TARGET_WEAK_NOT_IN_ARCHIVE_TOC
is nonzero, and if we see a noninline definition of a key method,
make the vtables nonweak.
