This fixes the bug reported in issue 9494 and adds a test case.

Closes: #9494

configure: move -fexcess-precision=standard to the internal cflags (#9496)

Follow-up to c5afa9303.

The GCC option -fexcess=precision is supported for C but not for C++.

Some users use ocamlc -c or ocamlopt -c to compile C++ source files,
causing errors since -fexcess-precision=standard was added to the
common C flags in commit c5afa9303.

This commit moves -fexcess-precision=standard to the internal C flags,
so that ocamlc -c and ocamlopt -c will not apply it to C / C++ source files.
