clang/0002-PATCH-clang-Make-funwind-tables-the-default-on-all-a.patch
Tom Stellard f94e02e6ae Only enable -funwind-tables by default on Fedora arches
.eh_frame sections confuse bpf tools, so -funwind-tables  shouldn't be enabled there.
There are other non-CPU arches where this could potentially cause problems, so be
conservative and only enable this on CPU arches supported by Fedora.
