spkg-configure.m4 for ecm

[dimpase]

it needs gmp, and is not a dependency of anything (besides sagelib)

To get this package on the system:

• Fedora: gmp-ecm-devel
• Gentoo: gmp-ecm - (but the version is too old in the main tree. Decent one in the sage-on-gentoo overlay)
• FreeBSD: gmp-ecm

checking the version by grepping the header, duh...

Does this really depend on #27212? I ask just because it's not clear to me exactly how, and this might be useful on its own as well.

gmp/mpir is a dependency of ecm! (and so not using system's gmp/mpir and using the system's gmp/mpir for ecm would lead to a lot of linking/loading "fun" with sagelib)

As for the contents of the ecm/spkg-configure.m4 itself, it looks fine to me at first glance, an I trust you've tested it.

A slightly more "sophisticated" approach might be build a test program which prints the value of the version, but in this case it's simple enough that just grepping for it should be good enough.
