[issue27490] Do not run pgen when it is not going to be used (cross-compiling)

[Thomas Perl]

Thomas Perl added the comment:

Repurposing this bug as "do not run pgen".

Documenting and using 'make PGEN_DEP=""' might also work; however, given that the configure script uses autoconf, and there's also code in place for PYTHON_FOR_BUILD, I've attached a patch that makes the PGEN dependency just a autoconf substitution -- this might make it clear and not depend on any make substitution features?

Patch attached against current Hg cpython default branch tip, a similar patch also applies against 2.7.
