A great deal of our objects are target specific. Almost everything depends on CONFIG_USER_ONLY too. This means that full compilation takes a very long time.

You might find ccache helps.  For this kind of testing, nearly every
compile should be a cache hit, so the slow part is limited running
configure, make and preprocessing, and the final link.

If it wasn't for ccache, my current testing setup would probably take days to complete :-)

For each patch, I do an rm -rf $(builddir) to also catch any possible bugs in configure and avoid false positives from old config-* files.
