configure: add missing dependency to libm.

Build broke when trying to compile with expressive debug CFLAGS (-g3).
This was root-caused to the lack of the "-lm" linker flag. By adding a
simple autoconf check we ensure that libm is linked.

More specifically, recent VEBOX changes depend on cos() and sin() math
functions.
