Comment (by kencu):

 gcc10-bootstrap will be able to build the current libgcc on all systems
 where the system can’t build it.

 It is not yet finished, and there’s a PR up for it. That is the reason
 this has not been done already.

 Once it is finished, the upgrade is not difficult; copy the steps I took
 to upgrade 10.6 to the current libgcc last year. One hour, max.

 gcc7 is not currently broken and I believe doesn’t need any fixing. It
 will be handled by the migration to libgcc12.



 Part of the reason gcc10-bootstrap is not finished is many questions about
 10.6-on-PPC etc. If we can just focus on one-step-at-a-time, progress
 might be forthcoming. catap I think threw in the towel at a certain point.
 Let him get it working on the easier systems first, then everything
 upgrades, then we can see about offbeat stuff like rosetta on SnowLeopard
 and 10.6-on-PPC.

 IMHO.
