From 5cddcc901beb3643f80f401fe9b6384081ea96eb Mon Sep 17 00:00:00 2001

Subject: makepkg: refactor absolute filename detection

Move the absolute filename detection to a new function to reduce code
duplication.

This patch also fixes the --allsource option that did not include remote
source files if they reside in $startdir instead of $SRCDEST.
