No, I don't think it is universal. This is the reason I did the move
of the file only in case it is to be found under lib64 but not under
lib.

I've tested the build to break with plain

./configure

and with

./configure --prefix=/usr --libdir=/usr/lib64

which I use normally to match my SUSE environment.

OTOH looking at Wei's recent patch to modify gmp's configure to
specify cross compilation I now believe the correct answer to my
problem is to add

--libdir=$(CROSS_PREFIX)/$(GNU_TARGET_ARCH)-xen-elf/lib

to the configure statement of gmp. I'll send V2 of the patch.
