I need to make some changes to src/Makefile.am on the gcc-5-branch so
this regenerates everything with automake-1.11.6 first.
Tested powerpc64le-linux, committed to gcc-5-branch.
* Makefile.in: Regenerate with automake-1.11.6.
* aclocal.m4: Likewise.
* configure: Likewise.
* doc/Makefile.in: Likewise.
* include/Makefile.in: Likewise.
* libsupc++/Makefile.in: Likewise.
* po/Makefile.in: Likewise.
* python/Makefile.in: Likewise.
* src/Makefile.in: Likewise.
* src/c++11/Makefile.in: Likewise.
* src/c++98/Makefile.in: Likewise.
* testsuite/Makefile.in: Likewise.
(No patch as these are all generated by automake.)
