Script no longer works for older version

[kubark42]

When installing somewhat older arm toolchains, for example 2009q1-161, https://sourcery.mentor.com/GNUToolchain/release830, the script won't work. It's hard configured to use MAJOR.MINOR-REVISION, which doesn't correspond to the old version style of MAJOR-REVISION.

You could roll back to previous versions that targeted earlier builds. As-is the Makefile doesn't try to interpret anything from the versions to decide what patches to apply, so patches just target the latest version.

@jsnyder Thanks for the suggestion. My experience was that I had to go pretty far back in time. The concern is that at some point in the future there will be a necessary bugfix which will be rolled back when checking out historic code.

As an aside, it was difficult in the beginning to figure out that I needed to get the SOURCE_PACKAGE and BIN_PACKAGE values directly from the website URLs. Not sure what there is to be done about it, since it's probably a lot of effort to automate that task.
