Subject[PATCH 3/4] objtool: orc: Skip setting orc_entry for non-text sections
Date
Orc generation is only done for text sections, but some instructions
can be found in non-text sections (e.g. .discard.text sections).

Skip setting their orc sections since their whole sections will be
skipped for orc generation.
