While building the LLVM 16.x branch:

... llvm-project/libc/src/unistd/linux/readlinkat.cpp:20:29: error: ‘ssize_t __llvm_libc::readlinkat(int, const char*, char*, size_t)’ aliased to external symbol ‘readlinkat’
   20 | LLVM_LIBC_FUNCTION(ssize_t, readlinkat,
      |                             ^~~~~~~~~~

The same problem also repeats with strcat, strcpy, bsearch, open, openat, strncat, pread, read, getcwd, readlink.
