Added runtime/spawn_subprocess.py. Force use posix spawn instead of fork, with API similar to subprocess. Using fork in runtime is incompatible with Xenomai, because memory is locked and this can lead to out of memory error.

<xhtml:p><![CDATA[This example shows how you can customize build process by using 'make'.
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.
