FWIW, it works fine on qemu-user-armel last time I tested. I could
build GHC completely on qemu-user for armel without any issues.

Btw, if anyone wants to test themselves:

$ wget http://users.physik.fu-berlin.de/~glaubitz/sid-sh4-sbuild-ghc.tgz
$ tar xf sid-sh4-sbuild-ghc.tgz
(compile qemu with --target-list=sh4-linux-user --static)
$ cp -av qemu-sh4 sid-sh4-sbuild-ghc/usr/bin/qemu-sh4-static
$ chroot sid-sh4-sbuild-ghc
(in chroot):
$ cd /root/ghc-7.8.4/utils/ghc-pwd
$ ghc Main.hs
