Comment (by Lokathor):

 Alright, I guess the downloads directories are made before they're filled,
 and they're filled based on platform popularity as well. At the time of
 this writing, the 7.10.3-rc1 directory has an ARM build, the 7.10.3-rc2
 does not, and the 7.10.3-rc3 directory is entirely empty.

 Using 7.10.3-rc1 I was able to build stack 0.1.7, and it seems to work. I
 also tried out another file that would always crash GHCi (but not GHC) in
 version 7.8.4, and using version 7.10.3-rc1 it did not crash ghci.

 I did however get a warning I've never seen before during the linking,
 about missing mapping symbols. I built another project just to be sure and
 it gave the same thing, all the messages are basically


 {{{
 /usr/bin/ld.gold: warning: cannot scan executable section 1 of
 /home/daniel/dev/haizod/.cabal-sandbox/lib/arm-linux-
 ghc-7.10.2.20151030/netwo_EsGuXlNmVtd2gsY9SXPuBb/libHSnetwork-
 simple-0.4.0.4-G2iPUu3gNst2JPWvkDR4bl.a(TCP.o)
 for Cortex-A8 erratum because it has no mapping symbols.
 }}}

 Things *seem* to run fine despite the warning though. I'm going to use the
 newly built stack to rebuild stack itself, which should give it a fair
 shake, but it takes like a day to build all the dependencies and the
 binary together, so I'll get back on results from that tomorrow.
