Interesting. However, I ran into some runtime segfaults caused by
--gc-sections yesterday. I didn't investigate further, but that makes me
hesitant to make --gc-sections the default. Something, somewhere, is
being broken by --gc-sections. It doesn't happen in all cases, though.
Only some of my programs are affected by it.

I should investigate this when I get some time.
