Ok, I couldn't wait. It doesn't help with the GHC issue, unfortunately:

address@hidden:~/ghc-7.8.4/utils/ghc-pwd# ghc Main.hs
[1 of 1] Compiling Main             ( Main.hs, Main.o )
qemu-sh4-static: /home/glaubitz/upstream/qemu/translate-all.c:175: tb_lock: 
Assertion `!have_tb_lock' failed.
qemu-sh4-static: /home/glaubitz/upstream/qemu/translate-all.c:175: tb_lock: 
Assertion `!have_tb_lock' failed.
Segmentation fault

I've also seen it lock up and strace showing it hanging in a futex lock.
