Building Haddock documentation panics with perf build on x86_64 Linux
After setting BuildFlavor = perf
in build.mk
compilation ends with a panic:

I've seen this problem before, but I thought that it was related to my patch. Now I got it on master branch and Luite reported the same problem on #ghc (log above is actually his).
A workaround for this is disabling building of documentation in "perf" section of build.mk
