glibc: allow (cross)-build on case-insensitive fs

...such as APFS.

The problem here is that a change inside the 2.39 patchset creates a
file `ADVISORIES` and also contains a directory `advisories/` and both
are considered the same file on APFS.

Reproducible with `nix-build -A pkgsCross.gnu64.stdenv.cc` on a
`aarch64-darwin` host.

Hence, excluding the file from the patchset as it is non-functional anyways.

Closes #303193
