Regenerate configure script when building mpsolve (autotools)

[d-torrance]

The configure script shipped in the tarball tries to run aclocal-1.16, but automake 1.17 was recently released and 1.16 is no longer available on some systems (e.g., Arch Linux).

For example (from https://github.com/d-torrance/M2-workflows/actions/runs/10797383121/job/29948523223);

WARNING: 'aclocal-1.16' is missing on your system.
         You should only need it if you modified 'acinclude.m4' or
         'configure.ac' or m4 files included by 'configure.ac'.
         The 'aclocal' program is part of the GNU Automake package:
         <https://www.gnu.org/software/automake>
         It also requires GNU Autoconf, GNU m4 and Perl in order to run:
         <https://www.gnu.org/software/autoconf>
         <https://www.gnu.org/software/m4/>
