how to manually discard some SDK content before bundling up the SDK?

[Robert P. J. Day]

   another off-the-wall question but i want to delete some content from
a standard SDK (sysroots/cortex.../usr/src) before creating the final
.sh script but, because of the slightly weird way this SDK is bring created
via "bitbake -c populate_sdk ...", i have little control of most of the
creation process other than right toward the end, where the easiest way
to do this would be to just sneak in a "rm -rf ..." command at the
appropriate time before the step that creates the tarball and appends it
to the .sh script in populate_sdk_base.bbclass.

   the SDK_PRE_INSTALL and SDK_POST_INSTALL variables would not quite
do it as i want to discard that content *before* creating the SDK so
that it is not in the tarball at all. i'm digging through
populate_sdk_base.bbclass right now, working backwards from the final
SDK creation step to see where i can get away with this, but if there's
a simple answer, that would be just ducky.

   in exchange for an answer, I'll proofread more documentation. :-)
