Nicholas Fraser : configure: Add --enable-build-id option.
Module: wine Branch: master Commit: 13ca3c883334801e2cadc699c2d35bb783e435dc URL: https://source.winehq.org/git/wine.git/?a=commit;h=13ca3c883334801e2cadc699c... Author: Nicholas Fraser <nfraser(a)codeweavers.com> Date: Tue Feb 16 16:15:32 2021 -0500 configure: Add --enable-build-id option. Build-ids are required for doing certain kinds of performance tracing. For example build-ids let Linux perf find the correct objects and transfer them to other machines via "perf archive".
