cross.bbclass: set autoconf's program prefix to keep TARGET_SYS and TARGET_PREFIX...

Currently, we rely on autoconf's implicit prefixing of outputted binaries
for -cross, but that names them based on TARGET_SYS, not TARGET_PREFIX,
which keeps the two tightly coupled.  By explicitly setting the prefix to
the latter, we get around that.
