This is in -next as b8c436bbef0f2a and breaks the build of all the arm64
selftests using nolibc:
clang --target=aarch64-linux-gnu -fintegrated-as
-fno-asynchronous-unwind-tables -fno-ident -s -Os -nostdlib \
-static -include ../../../../include/nolibc/nolibc.h \
-ffreestanding -Wall tpidr2.c -o

assumes that the nolibc include directory is in the include path, or
otherwise set up with a -I path, previously you just had to include
nolibc.h with the includes that are there working due to being relative
to nolibc.h. I'll send a patch for the arm64 tests.
It looks like the RISC-V selftests are also impacted, I didn't spot any
other users that didn't already have an -I.
