sin() and cos() undefined

[Steven M. Schultz]

Hi!

	I see the problem of the missing -I/usr/X11R6/include was fixed
	overnight - so now the plugins/x11 directory builds without error.
	Fantastic!

	It seems that the math library ("-lm") is not being added to the
	final link stage:

gmake: *** [vlc] Error 1

	I see that ./configure carefully checks for '-lm' but somehow
	the math library doesn't make it into Makefile
