Instead of running the nm output through grep and then running it
through awk again, run it directly through awk, and bail of immediately
if a non-absolute symbol is found.
Also, while we're here, avoid executing the indirect parsing code
if no __crc_* symbols are present at all, which shaves around 8-18% off
of the run time:
% for i in ./lib/modules/*; do \
echo "====== $i ====="; \
diff -u <(find $i | ./find-provides.ksyms.old) <(find $i | ./find-provides.ksyms.new); \
echo old:; find $i | time ./find-provides.ksyms.old > /dev/null; \
echo new:; find $i | time ./find-provides.ksyms.new > /dev/null; \
done

* find-provides.ksyms: Rewrite the "if nm | grep -q; then nm | awk"
with straight "nm | awk", update the awk script to return the exit code
accordingly, execute indirect symbol parsing only if inderect __crc_*
symbols are present.
* find-requires.ksyms (all_provides): Likewise.
