Most (all?) of these issues are solved by using a modern build system.
(No, make is not a modern build system.)

That's a good idea. Packaging the compiler toolchain should be automated
so that we don't have a packaging crisis every other release when
inevitably some script fails to do what we thought it would, or git got
itself into one of those wonderful obscure strange states that only an
expert can untangle.
