Comment (by ezyang):

 olsner: It's not, unless we install both "slow to link" and "quick to
 link" versions of static libraries. As you mention, this might be helpful
 anyway for loading statically linked libraries to GHCi.

 I *believe* my experiments showed that `--gc-sections` didn't really cost
 you anything if you weren't using `-split-sections`. So it should be fine
 to continue to pass it. Disabling it didn't really help with link times
 anyway.
