Indeed I suspect you are right; it should be fairly straightforward to
build GHC for your platform.

First you will need to build GHC itself. This will be a two-step
process:

 1. First build a cross-compiler [1] for your ARMv7L target on a machine
    with a working GHC (e.g. an amd64 machine).

 2. Transfer this compiler to your target and use it to build a native
    GHC

Let us know if you have any trouble.

Cheers,
