libbsd: Argument list too long

[Sebastian Huber]

The attached patch is necessary for msys2.

I still get the following error:

During handling of the above exception, another exception occurred:

waflib.Errors.WafError: Execution failure: [Errno 7] Argument list too long

The command line workaround is not applied.

We should see something like this:
