[libc-commits] [libc] [libc] Disable dl_iterate_phdr entrypoint for linux fullbuild (PR #131893)

[Roland McGrath via libc-commits]

https://github.com/frobtech created https://github.com/llvm/llvm-project/pull/131893

There are some issues with typedef conflicts between libc headers
and Linux kernel headers arising.  Disable building the new code
for Linux for now.
