I'm puzzled as to how this bug has lasted until now to be reported. It
must surely have broken things on a lot of C++ platforms, and it almost
certainly has never been right.
With MPIR 2.6.0 (and presumably [m]any earlier version[s]) this worked
for me (although I usally set CXXFLAGS manually, so wouldn't notice
unless I'm explicitly testing or compiling the C++ interface for a
non-default ABI):

from a release.
Just in case that's not yet on the todo list:
While --enable-cxx (and 'make check' with that) meanwhile works,
apparently the checks for the C++ compiler's capabilities are
currently missing, such that CXXFLAGS lack the ABI- and
machine-specific flags (-m32/-m64, -march=.../-mtune=...).
