Inclusion of features.h for armv7-unknown-linux-gnueabihf will, in
stubs-32.h, try to include stubs for hard or soft fp:
#if !defined __ARM_PCS_VFP
# include <gnu/stubs-soft.h>
#endif
#if defined __ARM_PCS_VFP
# include <gnu/stubs-hard.h>
#endif
gcc 13.3.0 as built by Yocto does not set __ARM_PCS_VFP unless
-mfloat-abi=hard is set. The build will fail as stubs-soft.h may not be
present.
Therefore, enable -mfloat-abi=hard when possible. gcc accepts it when an
FPU is selected (-mfpu=vfpv3-d16 in this case).
