[Buildroot] Per package src+build directory

[scdrj]

How do I set a custom src/build directory for a particular package?

I have tried OVERRIDE_SRCDIR, but it always performs rsync to the build
folder (makes an extra copy).

I want to perform the in-place build. 

Currently, I am doing it by creating a symbolic link in the build folder
from the original src directory and by manually creating various
downloaded/patched/extracted ".stamp_XXXXXX" files.

 That is not possible, period. Only the source can be overriden, but as you say,
it's always rsync'ed to the build directory.

 Is there a specific reason to want this? Doing the build inside the source
directory is not a good idea for many reasons.

 If it's for the size or the build time - normally, the compilation itself
should take a lot more time and produce a much bigger output, so the overhead
should be negligible.

 If it's because there's a large subtree that isn't actually used, *that* can be
avoided by using package-specific excludes, with
_OVERRIDE_SRCDIR_RSYNC_EXCLUSIONS (which is just a list of rsync argument, so
you can actually put anything there).
