gmp since 5.1.0 fails to build on ARM (freebsd)

[Łukasz Siemiradzki]

Hello,
 GMP since version 5.1.0 doesn't build on arm (sheevaplug) on Freebsd.
To omit the issue one has to use "--enable-assembly=no" option.
This affects both 5.1.0 and 5.1.1. Is it something which may be fixed in gmp?
Regards!
ŁS
