[oe] Building against a local git repo

[Michael Smith]

Hi,

I think in the past couple of months someone posted a trick for building 
out of an existing source directory, so changes can easily be gathered up 
and committed.

Basically, for local projects I'd like to occasionally break out of a 
development cycle of (edit, commit, push, bitbake) * n and just do (edit, 
bitbake) * n with a final commit and push at the end.

I remember the trick was being used for kernel development, and may have 
involved mangling S or WORKDIR, but that's about it; hoping someone might 
remember and save me some more hours scouring the archives :)

Thanks,
Mike
