Testsuite failure on mips64el, solved with '-fno-inline'

Hello,

I've had some issues with the package c-blosc. The testsuite started
to fail on mips64el. I found a solution, adding  '-fno-inline' in
CFLAGS in d/rules.

Does this seem to be a valid solution or, does it only hide a problem
with the source code?
There are a couple of things I find strange, the testsuite only failed
on mips64el and only after GCC-11 was the default compiler, (several
other packages have also been updated), though it doesn't need to be
related.

Regards,
Håvard
