Hello all!

I recently tried to upgrade our seq package in our internal build tool
from seq 2.2.6 to seq 2.2.9, and came across an issue.

If I understood correctly, the 2.2.9 version introduces a more modern
RULES_SNCSEQ, which gets installed through CFG, and the old RULES_BUILD
sources the new RULES_SNCSEQ for backwards compatibility.

The way that I'm building it, is by using INSTALL_LOCATION to install
seq in a separate directory, and then drop the original source code.

The issue that I have is that RULES_BUILD and RULES_SNCSEQ are both in
configure/ in the source code, but in the target directory, RULES_BUILD
gets installed in the target configure/, but RULES_SNCSEQ gets
installed under cfg/.

The way RULES_BUILD tries to include RULES_SNCSEQ is by including in
the same directory, which is not the case when using INSTALL_LOCATION.

My current ugly workaround is to have this in RULES_BUILD:

-include $(dir $(lastword $(MAKEFILE_LIST)))/RULES_SNCSEQ
-include $(TOP)/cfg/RULES_SNCSEQ

Which is not optimal since it will silently do nothing if no file is
found.

If I try to always include it from cfg/, the build of seq fails to find
the file, as it does not get installed early enough.

Is it possible to place RULES_SNCSEQ directly under cfg/ in the
upstream source?

Kind regards
