Hello,
RTEMS community is using ISL library as a part of GNU C compiler. Recently we have been hit by an issue of compiling GNU C compiler toolchain on the Apple M1 hardware. The issue is easily fixable by the patch below, but RTEMS community refuses to include the fix without a clear sign that upstream project (you) were contacted and asked either for patch acceptance or fixing the issue.
Could you be so kind and in next release use latest available autotools to generate configure script and associated files? This way, problematic config.sub file is generated with the proper support for Apple M1 hardware and everything should be working again.
Thanks!

This code is not in the isl repository, so there isn't anything to patch there.
