Partial bypass for 338803 Handling of dwz debug alt files or cross-CU is broken

This patch avoids dereferencing absori that are in other CUs than
the CU currently being read.
This avoids dwarf reading errors when reading inlined information.
The bypass results in inlined function being reported as
UnknownInlinedFun rather than the real correct function name.

--read-var-info=yes is still broken for unknown reasons
(probably type reading is doing some other cross-CU references ?).
