mjo: we had another patch in Gentoo that adds "-lgmp" to 4ti2gmp_LDADD.
I merged it into this one because otherwise they conflict.

Subject: [PATCH] build: link internal dependencies with .la files

When linking with internal dependencies the correct way is to add the
libtool archives (.la) files to the appropriate LIBADD or LDADD
variables.

This fixes a build issue when using slibtool instead of GNU libtool.
