Profiling GHC HEAD broken under OSX.

[pejo]

If I pull latest HEAD, with the following contents in build.mk:

BuildFlavour = prof

and then build under OSX it errors out with:

This does not happen to me with the build.mk without profiling from the developers wiki.

[igloo]

Thanks for the report; can you please paste the entire mk/build.mk contents for the build that doesn't work?

Replying to igloo: Here's the complete non-working build.mk:

BuildFlavour = prof

I initially tried the following diff to my working build.mk, but that gave the same error:

-GhcLibWays = v
+GhcLibWays = v p
GhcProfiled = YES

I'm no longer able to reproduce this bug under HEAD.
