libxl: explicitly check for libmath in autoconf
As well as explicitly add -lm to libxl's Makefile.
This is because next patch uses floating point arithmetic, and
it is better to state it clearly that we need libmath (just in
case we find a libc that wants that to be explicitly enforced).
Notice that autoconf should be rerun after applying this change.
