There were two problems:

I accidentally changed the variable name in the AC_ARG_WITH stanza from
configdir to xorgconfigdir, so specifying --with-xorg-conf-dir wouldn't
work correctly. Fix this back to configdir.

If neither --with-xorg-conf-dir nor --prefix is specified on the command
line, the $prefix variable doesn't contain "/usr/local" (the default
prefix) yet at this point but "NONE". So make install would attempt to
install 10-amdgpu.conf in ${DESTDIR}NONE/share/X11/xorg.conf.d/ . Fix
this by leaving ${prefix} verbatim in the default value, to be resolved
by make.

Also print the configdir value along with the values of other similar
configuration variables.
