See LLVM issue 61255 reported by Mark Millard, which turned out to ha= ve the same root cause as issue 61396. This is fixed in llvm-devel but not in= any release. With the attached diff to the FreeBSD copy of llvm-project I am able to bui= ld lang/gcc11, gcc12, gcc13, and gcc-devel in an armv7 jail. Without the fix = the ports builds hang because gcc built by llvm goes into an infinite loop.
