Yes, on my system I have /usr/lib/libmpfr.la which contains
dependency_libs=' /usr/lib/libgmp.la'.
If we add the following to the host system requirements, would that be
enough?
[ -e /usr/lib/libmpfr.la ] && [ ! -e /usr/lib/libgmp.la ] &&
echo "libgmp is missing"
I'm going to hold off releasing 7.5 until we get this settled.
