Comment (by nomeata):

 I managed to build 7.8.4-rc1 by telling GHC to use gold as the linker.
 Unfortunately, this was not straight forward, as setting
 CONF_GCC_LINKER_OPTS_STAGE2 using this patch had knock-on-effects:

 See #9873 for these problems and my (work-around-quality) patch.

 Probably yes.
