[Intel-gfx] [PATCH i-g-t] build: Make autoreconf honour ACLOCAL_FLAGS

[Damien Lespiau]

From: Damien Lespiau <damien.lespiau at intel.com>

When running autoreconf, it's possible to give flags to the underlying
aclocal by declaring a ACLOCAL_AMFLAGS variable in the top level
Makefile.am.

Putting ${ACLOCAL_FLAGS} there allows the user to set an environment
variable up before running autogen.sh and pull in the right directories
to look for m4 macros, say an up-to-date version of the xorg-util macros.
