Package: src:haskell-http-link-header
Version: 1.0.3-3
Tags: patch pending

Dear maintainer,
I see that the package fails to build ppc64el (but also powerpc/ppc64).
Running the build several times, I see it can fails differently and
especially during the compilation, so not sure about this particular
package being the cause.
There are some traces in dmesg like :

...
and looking at ghc's upstream, I see this bug opened :
https://ghc.haskell.org/trac/ghc/ticket/12537
On my side I can see :
$ gdb /usr/lib/ghc/bin/ghc /tmp/core.ghc_worker.52783.forge.1506076822

I don't know haskell at all, but as the above ticket mentioned problem
due to parallel build and atomic operations on Power, I think we have
a similar issue.
I tried forcing the build with -j1 which didn't break so far while
looping on the build of the package.
So here is a patch that can workaround that ghc issue on Power for now.
Regards.
F.
