(In reply to Mark Millard from comment #6)

Just for reference: I tested the build time for reverting the
code in my context:

# git -C /usr/ports/ diff lang/gcc12-devel/Makefile
diff --git a/lang/gcc12-devel/Makefile b/lang/gcc12-devel/Makefile
index 644abf2cbb86..fab28c952f80 100644
--- a/lang/gcc12-devel/Makefile
+++ b/lang/gcc12-devel/Makefile

The result was 01:38:45 for using bootstrap-debug:

instead of the earlier 04:06:27 for using bootstrap-lto-noplugin :
