The last FreeBSD version supporting mips64 is FreeBSD 13 which will be EOLed on April 30th. LLVM 23.1.0 release is expected to be August 25th according to the LLVM calendar. The usage of mips64 is less noticeable so it's hard to know if it is properly working, and even if it works, it is hard to test new features on FreeBSD mips64. Thus, remove support for mips64 on FreeBSD. --------- Signed-off-by: Minsoo Choo <minsoochoo0122@proton.me>
