libfcgi: link with libm when needed 



libfcgi uses frexp() and thus should link with libm, but fails to do
so.  Thus link errors with programs that use libfcgi (the bug does
appear only with uClibc, because the GNU libc provides frexp()
directly in libc.so).  Modify 0003-link-against-math.patch so libfcgi
links against math, instead of programs that need it.
