From: Andrei Gherzan <andrei.gher...@huawei.com>
Grub tries to force the compilation in softfp mode for some known target
CPU. That is because it doesn't use floats or doubles and there are
known limitations of using a configuration with hardfp. There are though
target CPUs that grub won't know how to configure failing with something
similar to:
| checking for options to get soft-float... no
| configure: error: could not force soft-float
This change relaxes a bit the COMPATIBLE_HOST restriction to only apply
for hardfp configuration even for arm7ve/a.
