commit 3661261f breaks arm64

commit 3661261fe17a8fe19681073889b5b36ec1ee823d,
"Always add -msoft-float to avoid compiler generating float
arithmetics." breaks the arm64 build.

-msoft-float is not a valid command line option for aarch64 (as far as
I can see, it is technically a target-specific option which just
happens to exist for most targets - including arm).

This setting will need to be conditionalised somehow.
An option that works for arm64 is -march=armv8-a+nofp+nosimd.

Would something like this be an acceptable workaround?:
