Fixed bug 978

Please add a #serial line as below to sdl.m4 and increase the serial number
with each revision of this file. This allows using aclocal --install, thereby
enabling automatic updating of sdl.m4 in SDL-based packages that distribute it.
# serial 1
The complete documentation and rationale for #serial can be found in the
Automake documentation:
