make: Explicitly enable FPU on ARMv7 builds

Browse source 
Starting with gcc-11, Debian's armhf compiler no longer builds with
a default -mfpu= option. Instead it enables the FPU via an extension
to the -march flag (--with-arch=armv7-a+fp). criu's Makefile explicitly
passes its own -march=armv7-a setting, which overrides the +fp default,
so we end up with no FPU:

    cc1: error: '-mfloat-abi=hard': selected architecture lacks an FPU
