Fix 'DoGetTextExtent - invalid DC' error

most likely this error happens only on certain wx backends.
GTK3+ on GNU/Linux is apparently one of them.
The problem is described in wxWidgets issue tracker.

Sometimes special steps need to be done to build entire project.
But it's not necessary to create another target in Beremiz every time you need to customize something in build process.  Just use for that 'Generic' target and describe all necessary steps in Makefile. 

For example, you can 
 - preprocess generated by Beremiz C source files, 
 - do some fancy source code transformation using any tools you want, 
 - use any compiler you want,
 - call static analyzers,
 - run integration tests on the project,
 - upload source code to external build server,
 - upload to the target and compile it there,
 - flash/transfer your compiled binary to the target,
 and much much more.
