Comment:
The problem is that both
{{{
libraries/base/dist-install/build/GHC/Float.o
libraries/base/dist-install/build/GHC/Float.p_o
}}}
used (and cleaned) the same
{{{
libraries/base/dist-install/build/GHC/Float_split
}}}
directory, so there is a race condition if both are built in parallel.
Fixed by:

* Add osuf to the name we use for the split dir
This avoids a collision between the directories we use when compiling
multiple ways, which in turn leads to a race condition in parallel
builds.
