If you need a Makefile.am snippet that does what you want but doesn't
override part of automake's output (yeah, it's not great style to have
an internal helper rule named so non-internally), then please use

distclean-local: distclean-ax-prefix-config-h
distclean-ax-prefix-config-h:
        rm -f _configs.sed t4k_common-config.h


Using the -local targets is the recommended way to extend targets, and
using a helper target avoids duplicate rule definitions if someone else
wants to extend the -local target as well.

The AX_PREFIX_CONFIG_H macro could distribute a fragment.am file with a
rule such as above (and the header file name suitably replaced by a
variable which could be AC_SUBSTed).

Cheers,
Ralf
