(mips64el) Cross-building GHC

[jugree at lavabit.com]

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:

utils/ghc-pwd/dist-boot --make utils/ghc-pwd/Main.hs -o
utils/ghc-pwd/dist-boot/ghc-pwd

How can I fix this? I can't find any information about this option.

Thank you.

PS: I only use free software (as defined by the FSF). Can I be sure
that I won't install any non-free programs during the process?
