[ARM] VFP: fix section mismatch error
Fix a real section mismatch issue; the test code is thrown away after
initialisation, but if we do not detect the VFP hardware, it is left
hooked into the exception handler. Any VFP instructions which are
subsequently executed risk calling the discarded exception handler.
Introduce a new "null" handler which returns to the "unrecognised
fault" return address.
