spkg-configure.m4 for iml

[dimpase]

iml only works with MP_LIBRARY provided in SAGE_LOCAL, at least this is the case on Debian 9.

they have a very old autoconf macro to detect GMP, which it particular won't work for libgmp in some arch-specfic location such as /usr/lib64/.

This breaks #27212. It works with GMP provided by the system if I just remove the call to their macro, re-run their bootstrap, repackage tarball.

While we are at it, it makes sense to update iml to the latest version 1.0.5 (we are at 1.0.4).

It should also get spkg-configure.m4

The easiest fix would be to skip the iml's testing for MP_LIBRARY if we use the one from the system.

But how does one test for this? Is there a variable (provided by #27212) in the environment that can be tested?

the patch I generate to conditionally disable checks for GMP is kind of big, as it's the result of autoreconf running...

spkg-configure.m4 has to wait until BLAS/LAPACK is sorted out
