Add libc++98convenience.la, libc++11convenience.la.
* src/c++98: New directory.
* src/c++11: New directory.
* acinclude.m4: (GLIBCXX_CONFIGURE): Add src-c++98, src-c++11.
* configure: Regenerated.
* Makefile.am (hosted_source): Add src-c++98, src-c++11 to SUBDIRS.
* Makefile.in: Regenerate.
* libsupc++/Makefile.am (AM_CXXFLAGS): USe XTEMPLATE_FLAGS for
-fno-implicit-templates.
* libsupc++/Makefile.in: Regenerate.
* src/Makefile.am (inst_sources): Move... C++11 files into
separate directory for libstdc++11convenience.la. Files are:
fstream-inst.cc, string-inst.cc, wlocale-inst.cc, wstring-inst.cc).
(sources): Move C++11 files. Files are: compatibility-c++0x.cc,
compatibility-atomic-c++0x.cc, debug.cc, functexcept.cc,
functional.cc, hash_c++0x.cc, hashtable_c++0x.cc, limits.cc,
system_error.cc, placeholders.cc, regex.cc, shared_ptr.cc,
mutex.cc, condition_variable.cc, chrono.cc, thread.cc, future.cc.
(libstdc++convenience.la): Add new target.
(SUBDIRS): Add c++11, c++98.
* src/Makefile.in: Regenerate.
* src/c++11/Makefile.am: New.
* src/c++11/Makefile.in: Generate.
* src/c++98/Makefile.am: New, C++98 files.
