so that gcc builds in a reproducible way in spite of indeterministic filesystem readdir order See https://reproducible-builds.org/ for why this is good. While working on the reproducible builds effort, I found that when building the gcc8 package for openSUSE, there were differences between each build in resulting binaries like gccgo, cc1obj and cpp because the order of objects in libstdc++.a varied based on the order of entries returned by the filesystem. Two remaining issues are with timestamps in the ada build and with profiledbootstrap that only is reproducible if all inputs in the profiling run remain constant Testcases: none included because patch is trivial and it would need to compare builds on 2 filesystems. Bootstrapping and testing: tested successfully with gcc8 on x86_64 [gcc] 2018-06-19 Bernhard M. Wiedemann <bwiedemann@suse.de> libtool: Sort output of 'find' to enable deterministic builds. --- pulled in libtool commit 74c8993c178a1386ea5e2363a01d919738402f30 because a full update appears to be too troublesome after 8+ years but we still really want that fix.
