(gl_FUNC_FTS): Don't require AC_HEADER_STDC, as we

don't use its results.
Don't check for fcntl.h, stddef.h, stdlib.h, string.h, unistd.h,
since we include them unconditionally.  Don't require
AM_STDBOOL_H, since stdbool is a prerequisite.
Don't require AC_C_CONST, AC_TYPE_SIZE_T or check for ptrdiff_t
since we assume C89 or better.
Don't require AC_FUNC_CLOSEDIR_VOID, AC_FUNC_LSTAT, or AC_FUNC_STAT,
as we don't use their results.
Don't check for fchdir, memmove, memset, strrchr, as we use
them unconditionally.
