With current behavior while scanning compile units the utility exits with
error if a unit does not contains an entry with name. However, some
packages, like arm-trusted-firmware, has entries without names. Since these
entries do not provide useful information for the mapping between binaries
to sources just skip them.

Depending on how a binary is build or post-processes the name attribute
can either be in a supplemental debug file (due to dwz) or be artificial
(due to LTO).

In this cases output warnings, but otherwise process as normal.
