builtins-bins' mipsel and mips64el builds failed with rc1, rc2 and rc3: https://buildd.debian.org/status/logs.php?pkg=llvm-toolchain-15&arch=mipsel and https://buildd.debian.org/status/logs.php?pkg=llvm-toolchain-15&arch=mips64el. It was building fine with llvm 14.
except from mipsel logs: https://buildd.debian.org/status/fetch.php?pkg=llvm-toolchain-15&arch=mipsel&ver=1%3A15.0.0%7E%2Brc3-1%7Eexp1&stamp=1661462547&raw=0
