bug#1705: 23.0.60; parallel build failure: `mh-e' was not provided

[Markus Triska <markus.triska@gmx.at>]

A parallel compilation (-j 2) with today's CVS version aborted with:

   In toplevel form:
   mh-e/mh-folder.el:34:1:Error: Required feature `mh-e' was not provided
   Wrote /Users/mt/emacs/lisp/mh-e/mh-e.elc
   Compiling /Users/mt/emacs/lisp/mh-e/mh-funcs.el
   make[1]: *** [/Users/mt/emacs/lisp/mh-e/mh-folder.elc] Error 1
   make[1]: *** Waiting for unfinished jobs....
   make[1]: *** Waiting for unfinished jobs....
   No MH variant found on the system
   Wrote /Users/mt/emacs/lisp/mh-e/mh-funcs.elc
   make: *** [lisp] Error 2

After another "$ make -j 2", the compilation proceeded without errors.
The full compilation log is available from:

I have seen this problem only once so far in many tries.
