What are the criteria for section gc?
For example, if I'm the X server, I have a bunch of symbols exported
from the binary that the drivers are expected to call, but that are
never called from the server itself. Does marking a function
__attribute__((visibility("default"))) mark it as used from the garbage
collector's perspective?
