freerdp3 fails to cross build from source, because it fails to locate
generate_argument_manpage. During cross builds, the build system expects
to be pointed at a prior native build providing this file. I tried
implementing this as intended, but the native build is difficult to
strip down. We only need this one file, but we end up compiling half of
freerdp3. Worse, this requires duplicating half of its Build-Depends
with a :native annotation.

I am thus proposing to manually build that one generate_argument_manpage
binary. Doing so is manageable and fast. I'm attaching a patch for your
convenience. What do you think?

Hi,


FreeRDP maintainer here.

your patch will produce a buggy manpage.


The generation requires the `config.h` variables of your cross build to
be included.

otherwise the manpage will show the wrong (or missing) argument
documentation for the build.
