Let make do it.
Seriously, I've never done any performance measurements to see how or
if we could speed up generated Makefiles. If we did do this then I'd
prefer to generate a fast Makefile at the expense of automake's
runtime. make will be run many more times than automake, even for
people modifying Makefile.am.

I don't recall this precise case, but sometimes these changes are in
response to a particular bug report.
Do you have a way you want to change this code? I don't think we can
use VPATH here. And, unfortunately, not all make implementations like
`./acconfig.h' (or at least, so ISTR).
