perl: disable tests on Darwin, refactor stdenv.lib usage

There was a mysterious error, which I don't have resources to investigate:

Removing test lib/Net/hostent.t
sed: -i: No such file or directory
mu: fix build by using older texinfo
v8: fix build with newer gcc
perl: re-enable the postPatch hook on Darwin

The problem was that sed(1) variants other than GNU sed require a backup suffix
to the -i option.
perl: revert "re-enable the postPatch hook on Darwin"

This reverts commit 1778200519a18ae00751ab3015d0e665373c32f6.
Apparently, the sed -i syntax is different from what I thought, because
now the build fails on Darwin, saying:

  sed: -i.bak: No such file or directory

See http://hydra.nixos.org/build/5829944/nixlog/1/raw for more details.

pkgs/build-support/cabal: fix the logic of the 'noHaddock' flag that was broken in 27905ce17e1b1aed55edbff5856082b8c1b51fc7
Merge remote-tracking branch 'origin/master' into stdenv-updates.
pkgs/build-support/cabal: unconditionally set $LANG to "en_US.UTF-8" during Haskell builds

Haskell tools like Haddock require a locale to be configured, so do some
regression test suites.
