Hi Guix!
While investigating a libstdc++.a reproducibility issue, I found that libtool prior to 74c8993c (first included in version 2.2.7b, link: https://git.savannah.gnu.org/cgit/libtool.git/commit/?id=74c8993c178a1386ea5e2363a01d919738402f30) did not sort find output. It seems that many packages (including all released gcc versions so far) are bootstrapped with a libtool < 2.2.7b.
There are probably many ways to approach this, and I propose that we could simply use a somewhat strict regex find and replace on ltmain.sh.
Would love feedback and better ideas!
Cheers,
Carl Dong

Right, good ol’days!

Ouch, I didn’t expect this.

Yes, we could add a standard build phase to do that. We just need to
make sure we get the regexp right so it doesn’t break newer ‘ltmain.sh’
scripts.
WDYT?
