X-Git-Tag: v1.11b~195

maintcheck: take advantage of some GNU make features

We can do so now that our maintainer checks require GNU make
unconditionally.

* syntax-check.mk (ams, xtests): Redefine as "immediate variables",
using the GNU make $(shell ...) builtin.
(maintainer-check-list-of-tests): Take advantage of GNU make "-C"
option.  Don't use $(AM_MAKEFLAGS), we shouldn't need it with GNU
make.
