Hi Guix!

While investigating a libstdc++.a reproducibility issue, I found that libto=
ol prior to 74c8993c (first included in version 2.2.7b, link: https://git.s=
avannah.gnu.org/cgit/libtool.git/commit/?id=3D74c8993c178a1386ea5e2363a01d9=
19738402f30) did not sort find output. It seems that many packages (includi=
ng 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
