  Stop using $run for anything other than testing compiled tests in Configure.  
  When cross-compiling we want to run miniperl etc on the compile host\, not the test target

Hence\, there is a risk that if we apply your patch\, we will simply be back to where we were in 2012.

You are right. Please\, close the ticket.

My problem doesn't come from a new version of Perl\, but it comes from a new toolchain.

With the "good" toolchain\, the generated utils/Makefile contains PERL = ../miniperl so no need of RUN.
