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.
