Do you have any reproduction instructions? A commit hash?

It's AArch64 musl, but hard to tell what's going on here probably without specifics. What distro is this?

cross compiling.

the problem is that musl header redefines what linux kernel header defines. Since llvm includes the header for twice, it stops build

sys/prctl.h redefines linux/prctl.h

@lakshayk-nv Not sure if you've seen this. Can you take a look?
