Really a detail, but for clarity I would change “xlibc” to “libc”,
because this argument denotes a C library, not a cross-compiled C
library.

Ditto in other places.

You can send an updated patch or I can make this change on your behalf
if you prefer, let me know!

This procedure is starting to look weird.  :-)  I wonder if we should
inline it at the call sites, but we can look into it later.

Thanks,
Ludo’.
