No. That is not backward compatible. 
In the worst case we can add the compiler dir, but as the last.

But even so:
it is not done on unices to search in the binary directory for config
files. That's a windows thing.

Don't introduce this on unices:
You should accept & follow the rules of the platform you're working on.

If you really want that, create a wrapper which sets PPC_CONFIG_PATH to the
compiler bin dir. But I strongly advance against this.
