On my systems without perl,  PERL is set to something like

  ${SHELL} '/usr/src/coreutils-9.0/build-aux/missing'  perl

which causes condition at line 70 in configure.ac to fail, resulting in
incorrect detection of perl and subsequent build failure. Suggested fix:

Thanks for the bug report and suggested fix. On the whole I think it'd 
be better to address the nearby FIXME instead, so I did that by 
installing this into Gnulib:

https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=8220e0f0b5f46ff61e1d19f8a1614508fa162abd

and the attached into Coreutils. Please give it a try. In the meantime 
I'll assume this will fix the bug for you and so am boldly closing the 
bug report; if that's wrong we can reopen it.
