Parallel-make safe build of mono bindings

[Dennis Schridde]

Mono bindings may fail to build in parallel-make scenarios because the api.xml file gets partly overwritten before codegen runs. Attached patch fixes this.

I still get mono binding failure with this patch and make -j4. Make runs fine.

It also seems to fail randomly for me as well. Both with an without the patch. Here's the relevant output (I think):
