When run in the Git source directory, this will find the perl/
subdir.  If the user gives an absolute path to the perl binary,
there will be no auto-detection anyway, so I think we don't need it.

It is not needed but might be useful if PERL is user configurable
variable and can contain either full path or basename. For example this
code

    test "$PROG" || PROG=prog
    PROG=`path_find "$PROG"`

works with these cases

    $ PROG=/usr/bin/program ./configure
    $ PROG=program-1.2 ./configure

I will add that.  For the compiler, the script already checks $CC.
I wonder whether

  --with-perl=...
  --with-python=... 

is more common (more similar to autoconf) than

  --perl=
  --python=
