(mips64el) Cross-building GHC

Hello.

I would like to port GHC to mips64el. I have never tried
cross-building before. So I will probably post more questions later.

Actually, I am not sure that I am using the right term. I am going to
use my i686 machine to build GHC for mips64el. In terms of this
page(0):

B = i686-unknown-linux
H = mips64el-unknown-linux
T = mips64el-unknown-linux

Is the above correct?

What I did:

1. Downloaded this(1) tarball (on i686) and unpacked it.
2. Executed the following commands(2):

ghc-7.6.1$ cp /bin/pwd utils/ghc-pwd/ghc-pwd
ghc-7.6.1$ perl boot
ghc-7.6.1$ ./configure --enable-hc-boot --build=i686-unknown-linux
--host=mips64el-unknown-linux --target=mips64el-unknown-linux

Output:

checking for gfind... no
checking for find... /usr/bin/find
checking for sort... /usr/bin/sort

Awesome.  I have a MIPS-based netbook (lemote yeelong thing) and got the GHC 
port from Debian on it, but of course it's a just-barely-works build :)

What do you mean by barely-just-works? Anything besides:
 * no GHCi support and
 * bad performance due to the lack of a native code generator
is probably a bug that we (the GHC maintainers in Debian) would like to
know about.

Greetings,
Joachim

Sorry, I did not mean that to sound so negative.  I'm really glad you guys 
have a build for my esoteric machine at all :)  I was, in fact, referring to 
the lack of GHCi/TH/DPH support, and IIRC it uses the old via-C instead of 
LLVM, but I could be wrong about that.  More eyeballs on porting to the 
architecture would certainly not be a bad thing.

I haven't experience any actual bugs yet in my yeeloong GHC.  Thanks for 
providing it.

Could you help me to find a workaround for the mentioned error?
