Haiku has math functions in libroot.so and no libm.so.
A more elegant solution would be an autoconf check for some math function
actually used. That would avoid linking against -lm on Mac OS X as well,
where libm.dylib is a symlink to libSystem.dylib only.
In its present form, the patch does not change behavior of other platforms.
