Benjamin Block 4941fc15c0 zfcpdbf: test-compile the script during the build using perl -c ...

For a slightly easier development loop add a pseudo compilation of the
zfcpdbf Perl script. This will run the Perl interpreter in syntax-check
mode:

  -c   causes Perl to check the syntax of the program and then exit
       without executing it.  Actually, it will execute any "BEGIN",
       "UNITCHECK", or "CHECK" blocks and any "use" statements: these are
       considered as occurring outside the execution of your program.
       "INIT" and "END" blocks, however, will be skipped.

Additionally add the `-w` switch when the Make variable `W` is `1`. This
will print additional warnings about dubious constructs (according to
Perl).

So this pseudo compilation only happens whenever the script is changed
during development create a file `.zfcpdbf.ct` as a result so we can
describe the relationship and dependency in Make. This file can be ignored
otherwise.
