A few extra details:
I noticed this while trying to build an Ada runtime for VxWorks from the
current mainline.
A few sources referenced by the Makefile are missing and I'm about to add them.
Some of them rely on having a definition for EH_FRAME_DEBUG_SECTION, which we
don't have with DWARF_UNWIND_INFO defined to 0, causing the build to fail.
We have been using the patch in-house for years, and I verified that it allows
the runtime build to go past the failure point with mainline.
