sci-mathematics/4ti2: add 1.6.10

I'm reluctant to include an invasive build patch in case upstream
rejects it, but I haven't gotten a response on the PR, and this isn't a
fast moving project, so I'm starting to think I should just fix it.

+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.
