Perl is required on the build system in order to run build-aux/help-extract.pl, which could be rewritten in e.g. sh+awk but it would be a pain in the neck.  "Quit using help2man" is on my long-term TODO list but I cannot make any concrete promises and the most likely replacement is pod2man (possibly together with gcc's texi2pod), which also requires perl on the build system.

I'm not aware of any existing convention for how to distinguish host perl from build perl.  How would you like us to do it?

When compiling autoconf in cross builds the location of the target perl binary might be different to the host perl binary used at build time.

However, the same variable is used for both of these: autoconf.in uses @PERL@ in the shebang (target perl) but man/autoconf.w executes $PERL at buildtime (build perl).

Might be possible to just remove the use of PERL in man/local.mk?
