The files you link to don't make much sense to me (they do not look
like patch diffs) but they seem to suggest hard-wiring configure results
into the source code, which does not sound like an acceptable solution
from our standpoint.

The approach we've suggested to people in the past is running configure
for each architecture and then building against that copy of
pg_config.h, or more likely combining the .h files with arch-specific
#ifdefs. You can find more info in our list archives --- the most
relevant thread I could find easily starts here:
