From: Arnd Bergmann <[email protected]>
With extra warnings enabled, clang complains about the redundant
-mhard-float argument:
clang: error: argument unused during compilation: '-mhard-float'
[-Werror,-Wunused-command-line-argument]
Move this into the gcc-only part of the Makefile.
Fixes: 4185b3b92792 ("selftests/fpu: Add an FPU selftest")
