It wasn't. It was filtering -msoft-float out of the compiler flags,
which then left the ABI up to the toolchain default, which was hardfp
for one of the Raspberry Pi Foundation's toolchains - the same one that
caused the error messages quoted above unless -msoft-float was removed
from the compiler options.
