[oe] RFC: Library file extensions

[Richard Purdie]

Hi,

As some may have gathered I made some experiments with using Poky to
cross compile things to run on the iPodTouch which is arm-apple-darwin.
THe good news is they were successful however Darwin creates some
interesting challenges for OE, one of them is the dynamic libraries
being called *.dylib, not *.so.

I've had the following patch in Poky to assist with this problem. It
would need to be rolled out over all .bb files with custom FILES
eventually but it has the advantage that can happen over time so the
question is more whether this is a good idea and whether the approach is
acceptable?

We would probably hit the same issue with windows .dll files and this
solution would solve that too.

Comments welcome...

Cheers,

Richard
