Hi.

I don't think this function is necessary; and the sha256 hash is fixed
here but it would in fact depend on the commit passed as argument to the
function.

So I would rather put the 'origin' field in this package building the
C library. And as the purpose of this package is to build the
libasyncprocess library, I would just call it "libasyncprocess".

Then the sbcl-async-process package could be simplified by inheriting
from the libasyncprocess package, and modifying the 'name',
'build-system', 'inputs' and 'arguments' fields.
