While trying to build haskell-nettle on mips/mipsel architecture,
build fails on testing with an error:

The reason for this error is that ANN pragmas used in haskell-nettle
source code.  Some architectures like mips, do not have support for
GHCi and without GHCi support, these parts of code are
treated as errors.

A patch that adds DEBIAN_NO_GHCI switch
in order to enable successful build of haskell-nettle for mips/mipsel, 
is attached.


Could you please consider including this patch?

Best regards,
Dejan
