Rich Felker 56764601af fix dynamic linker path file selection for arm vs armhf
the __SOFTFP__ macro which was wrongly being used does not reflect the
ABI (arm vs armhf) but just the availability of floating point
instructions/registers, so -mfloat-abi=softfp was wrongly being
treated as armhf. __ARM_PCS_VFP is the correct predefined macro to
check for the armhf EABI variant. this macro usage was corrected for
the build process in commit 4918c2bb20
but reloc.h was apparently overlooked at the time.
