The debuginfo inside the static archives used to be stripped because
it wasn't very useful. The change didn't just stop the stripping it
also updates the debuginfo to be actually useful to
include. Specifically it rewrites the debuginfo to include to correct
source file paths as shipped in the corresponding debugsources package
(which also means those might now include more source files).
