Looks like your libfaad.so isn't linked to the maths library. Mine isn't
either...
$ ldd /usr/lib/libfaad.so.0.0.0
        libc.so.6 => /lib/tls/libc.so.6 (0x0060e000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x005f6000)

That's a bug in libfaad, or the package itself.
CFLAGS="$CFLAGS -lm" before the test in configure.ac should fix it.
