* grp/initgroups.c (initgroups) [NGROUPS_MAX != 0]: Always use sysconf

	instead of the constant NGROUPS_MAX.  That way, the limit can be
	raised in the kernel configuration without having to recompile libc.

	* sysdeps/posix/euidaccess.c: Don't #include <limits.h> or try to
	define NGROUPS_MAX; we don't use it here.
