I think the goal was to avoid hitting commandline limits on windows -
where the build indeed did hit those multiple times, both in make
itself as well as in cygwin. But those cases are with lang=all
usually, and are much better avoided by using temporary files with the
lists of files to process, instead of listing hundreds of paths in the
invocation line.

I also think it is not really that useful anymore, given that the
paths are exported in config_host.mk anyway and can already be
referenced using those variables.
