I remember adding 6.3 to the sage-on-gentoo tree for GMP-5

I'll have to check my inbox for the details. I imported it on the 7th of
July
because it said it was compatible with GMP-5 and one of our user was using
that.
The user then reported that he still couldn't get ECM to build and I
introduced the
fix above the next day which solved the problem.
A possibility is interference with by a patch to GMP Gentoo side.
On a positive note ECM 6.3 is the default in sage-on-gentoo since the 3rd
of August so it has been extensively tested on x86, amd64 and ppc. However
assembler code is at the user's discretion.
