--- Comment #1 from Andrew Roberts <andrewm.roberts at sky dot com> ---
Looking at the toplevel Makefile.in the gmp targets (maybe-configure-gmp,
configure-gmp etc)
use:
--build=${build_alias} --host=none-${host_vendor}-${host_os}
--target=none-${host_vendor}-${host_os}
where as isl, mpfr etc all use:
--build=${build_alias} --host=${host_alias} --target=${target_alias}
Presumably there was a historic reason for this, is it still valid?
As my previous comments say, this seems to have started causing problems on ARM
from GMP 5.1 onwards.
