That change has not removed the targets that are needed to build pdfxtex.
Basically, pdfxtexdir/pdfxtex.mk was empty, so pdfxtex could not build.
So, I have removed pdfxtex from fmtutil.in etc. so that the missing
build rules for pdfxtex don't cause any trouble.

So, the real fix would be to put something useful into
pdfxtexdir/pdfxtex.mk.
