[Ohrrpgce] SVN: teeemcee/10025 scons: Reduce game/custom.exe size by 1MB by compiling with --gc-section

[Ralph Versteegen]

I hope it's not a whole month, but if we delay by some weeks it'll be nice
to not be in the mindset of squeezing things in at the last minute, which I
always fall into!

Oh, and Etheldreme+1 never happened. That's too bad; there are a raft of
bugfixes in nightlies. If we could do stable releases with minimal effort I
would have suggested we release it a week ago despite the absurd delay.
(I actually have a couple more finished bugfixes in an unmerged branch
somewhere... so many branches)
