[PATCH] Makefile.am: add include dir for AC_CONFIG_MACRO_DIR to work

[Maciej Wolny]

da331647269ee9d73c4008ae901d107320bdc8d1 added a compatiblity macro for
old versions of pkg-config. However, the file in which that macro
resides was not included. From the autoconf docs: "Note that if you use
aclocal from Automake to generate aclocal.m4, you must also set
ACLOCAL_AMFLAGS = -I dir in your top-level Makefile.am.".

Before this, ./autogen.sh would fail for me (with autoconf 2.68 and
pkgconfig 0.25).
