Linux upstream has started needing libelf-dev. Without it, recent tip fails (in our configuration) like this:
Makefile:938: *** "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel". Stop. It is not clear exactly when this requirement was introduced. Our bisector said: Bug introduced: 91a6a6cfee8ad34ea4cc10a54c0765edfe437cdb Bug not present: 1c9dbd4615fd751e5e0b99807a3c7c8612e28e20 but the "introduced" commit is a merge of a large branch, so it's not blaming a specific commit. None of the commits in that range mention libelf so the most likely reason is a consequence of a change to some configuration interactions (ie, probably, an expansion of the scope of an existing dependency).
