use the provided m4/ directory for aclocal

[GoogleCodeExporter]

autogen.sh does not use -I m4 when calling aclocal so the
LIBNFC_ARG_WITH_DRIVERS, LIBNFC_CHECK_LIBUSB and LIBNFC_CHECK_PCSC macros
are not expanded on my Mac OS X system and Debian testing system.

Proposed patch (tested on Debian and Mac OS X):

Hello,
Thanks for this report.
Actually you are trying to remove autogen.sh in order to use autoreconf. Could 
you
try to run "autoreconf -vis" instead of "autogen.sh" mainly on Mac OS X (Debian 
is
already confirmed to work.)

OK, "autoreconf -vis" does work for me on Mac OS X Snow Leopard.

Note that I use my own versions of autoconf, automake and libtoolize. The 
versions
included in Snow Leopard where too old for other projects I use.

Great ! In r401, autogen.sh have been deleted, developers should now use 
"autoreconf
-vis" but i have applied your patch in r400 in case of some users reports 
problems
with autoreconf command.

Thank you Ludovic for your help. (And indirectly, thank you for ACR122 support 
in
libnfc ;) )

PS: I made a mistake in my previous comment: s/Actually you are trying/Actually 
we
are trying/
