Comment:
@q66 perl is only required in coreutils to run the test suite.

```
# The test suite needs to know if we have a working perl.
# FIXME: this is suboptimal.  Ideally, we would be able to call gl_PERL
# with an ACTION-IF-NOT-FOUND argument ...
cu_have_perl=yes
case $PERL in *"/missing "*) cu_have_perl=no;; esac
 if test $cu_have_perl = yes; then
  HAVE_PERL_TRUE=
  HAVE_PERL_FALSE='#'
else
  HAVE_PERL_TRUE='#'
  HAVE_PERL_FALSE=
fi
```
