site: set getcwd() behaviour for long paths for glibc / musl
In glibc, getcwd() handles long file names properly, on
musl, getcwd() only works up to PATH_MAX directory depths.
Configuring the autotools (gnulib) test result here allows
coreutils to compile more optimised code for both platforms,
rather than being pessimistic and re-implementing everything
itself.
The difference in behaviour is because both do the kernel
getcwd syscall (which only supports up to PATH_MAX), but
glibc implements fallbacks for longer paths, while musl
doesn't.
