Bug#811554: haskell-hslua: Please don't build-depend on libluajit-5.1-dev for unsupported architectures

[Steven Chamberlain]

Hi,

luajit can actually build on kfreebsd-amd64, if the maintainer could
add that back into the Architectures list now please:
https://bugs.debian.org/744948

I don't know why it was removed from the Architectures list?  Just
because it FTBFS, it should be adequate to request ftpmaster removal
(if necessary, e.g. if blocking testing migration), but let every new
version try building in case it is eventually fixed.

luajit may actually work on some of those architectures;  who will
test the package on e.g. x32 to see if it might work there?  And on
newer architectures as they appear?  From my point-of-view as a porter
it is much better to try to build and fail.

(There *may* be some really good reason to think luajit isn't portable
so I'm open to suggestions.)

The lack of tests running during the build are a concern maybe, so it
might successfully build something that doesn't work on some arches.
But still, it is unlikely to ever be tested at all, if users of a port
have to build it themselves (and dependencies, if they took the same
conservative approach).

Could we rather have that for luajit first:  enable luajit builds on
any architecture, except for a blacklist of arches where we know it
definitely does not work (if any)?

Thanks,
