I've looked at the version of libc I have and its 2.24:
$ /lib/libc.so.6
GNU C Library (GNU libc) stable release version 2.24, by Roland McGrath et al.

I then cloned the gcc 2.24 sources as of today and the code that
24e2b1cede1952d7d4411a3cafd25dd8593dab9f reverts is still there. I
also took a quick look at the Arch Linux glibc package
and don't see any local patches.

Therefore I assume it hasn't been patched.
