Two solutions:
*) Do the build of the component you're actively working on outside of
Buildroot. Typically, when I do kernel hacking, I do it outside of
Buildroot, and I use Buildroot only as a final integration
mechanism, to make sure that the system build process is
reproducible. But not during development.
*) Use the OVERRIDE_SRCDIR mechanism, as documented in
http://www.elinux.org/images/2/2a/Using-buildroot-real-project.pdf,
slide 41.
Best regards,
Thomas
