Description:

mold 1.3.0 and above ships with a patched libtbb that contains fixes for LTO stability under heavy load. See notes here:
https://github.com/rui314/mold/releases/tag/v1.3.0

The current build does not take advantage of it because it uses the system libtbb by setting SYSTEM_TBB=1.

mold should be built with SYSTEM_TBB=0 to take advantage of the LTO stability fixes.

This task depends upon
