perl-module: Add --without-perl-module configure flag.

The built Perl module is not useful for cross-compilation.  By default it
is disabled for cross-compilation, but cross-compilation to Mingw32 is not
always detected as cross-compilation (since some Linux systems can run
Windows binaries directly, via Wine), so this option helps in such cases.
