I am not shure, but I think fpcmake creates a package description file. So
fpcmake is needed for creating packages.

I did add this feature.

Without this error detection, what's happend is that, becuse $(FPCMAKE) is
empty, the following command is attempted:

-p -Twin32 ...

Since a preceding hyphen, tells make to ignore errors, this is a source for
hard to find bugs.

The error detection could have been done when the makefile was preprocessed,
but then the abscense of any tool would have stoped make. This solution
makes it possilbe to detect that kinds of error at runtime, only if the tool
realy is about to be used.

Perhaps you can test if $(FOCMAKE) is __missing_command__ instead of testing
if its empty.
