I'm trying to implement this currently, and have two observations:

1) seems to have .eh_frame even with default options currently.
GCC insists generating it for the PLT. Though otherwise it's empty.
This is on gcc 10.3.1.

2) .debug_frame is 109944 bytes, while .eh_frame_hdr + .eh_frame is
83832. The size difference seems to be because of CIE entries not being
merged for .debug_frame.
