 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 dicumentation in "perf"
 section of `build.mk`.
