Pass -no-undefined flag to autotool based spkg

[jpflori]

A bunch of spkg using autotools do not build shared libraries of Cygwin because -no-undefined flag is not passed to libtool:

• cddlib (update in #13026),
• eclib (fixed in #13325 with new upstream version),
• ecm,
• givaro (updated in #9511 and #13164, try ​http://www.infres.enst.fr/~flori/sage/givaro-3.7.1.p0.spkg, reported upstream should get in),
• glpk (updated in #12703),
• gsl (mentions of -no-undefined in src code but only for MinGW, reported upstream at ​https://savannah.gnu.org/bugs/index.php?37894),
• iml (updated in #748, try non updated at ​http://www.infres.enst.fr/~flori/sage/iml-1.0.1.p15.spkg, not sure upstream still exists),
• libfplll (see #13804 for a quick (different problem) fix and #12835 for the fact we ship a really old version, should update it before thinking about the problem here),
• linbox (updated in #12883, try ​http://www.infres.enst.fr/~flori/sage/linbox-1.3.2.p0.spkg, reported upstream),
• lrcalc,
• mpfi (will be fixed upstream),
• ntl (broken and fixed in #11635, no real upstream anymore as far as I understand).

For the updated fixed linbox, you'll need first iml, and then updated fixed givaro together with dependencies at #12840 and #12841.

Wrong button...

The Linbox spkg from #12883 changed, so the one linked here is now outdated.

[jpflori]

The linbox spkg is now rebased on top of #12883, but nothing is committed. By the way, the spkg there lacks an hg tag.
