Subject: [PATCH] [buildsystem] distribute cxx11_constexpr.m4

The check for constexpr was not copied into the distribution.
Unfortunately, the autotools will only warn about a missing macro, but
give valid results otherwise. This patch adds the cxx11_constexpr.m4 to
Makefile.am, so that it is distributed on "make dist".
