mkdir-p module

[Ralf Wildenhues]

The mkdir-p module currently
- lists m4/chdir-safer.m4 but the file does not exist in CVS,
- defines macros gl_FUNC_LCHMOD and gl_CHDIR_SAFER but does not use
  them (they are needed though).

Cheers,
Ralf

        * mkdir-p.m4 (gl_MKDIR_PARENTS): Require gl_FUNC_LCHMOD and
        gl_CHDIR_SAFER.
        * m4/chdir-safer.m4: Sync from coreutils.
