Unix Makefile: Make sure to use $(PERL) when running ./Configure

For consistency, it's better to use the perl that was specified to
Configure last time it was called.

Use case:

perl v5.8.8 was first along $PATH, perl v5.22.2 was available and
specified as: PERL=/opt/local/bin/perl ./config.  When make wanted to
reconfigure and called './Configure reconf', configuration broke down,
complaining about a perl that's too old.
