[BOLT] Stripping .bolt.org.eh_frame and .bolt.org.eh_frame_hdr sections

[s-dag]

Hi,

We are running on a constrained environment and while looking for size savings, and noticed BOLT leaves .bolt.org.eh_frame and .bolt.org.eh_frame_hdr sections in the binary when applying --update-debug-sections. These .bolt variant sections are not used. Is there a reason why we shouldn't strip them? As a follow up question, should BOLT strip them automatically?

These are allocatable sections that can't be stripped easily like e.g. .debug_*. That said, there is work happening on removing those sections.
