Cabal-1.18 in ghc-7.8 does not support -j

The key idea is that we define:

    type IO a = HasCallStack => Prelude.IO a

and voila, call stacks are maintained across all IO!  You can
look at the stacks using -v"debug +callstack".

There are a number of IO functions for which the call stack is
never used.  They are explicitly annotated using NoCallStackIO.
Maybe some day they will use call stacks and we can change their
types.  Similarly, there are a number of functions which do
have type IO, but then suppress the redundant constraint error
using "_ = callStack". Maybe some day we will attach call
stacks to the exceptions we throw.

For ghc-8 fixes.

1. Assign the var and export afterwards.

2. Use mktemp instead of home-grown solution. The mktemp flags we use
   are supported on FreeBSD, Solaris, OpenBSD, and Linux.

The order of the 2>&1 and the redirect matters. The 2>&1 has to be last.

Don't use variables in the printf format string.
Use printf "..%s.." "$foo".

This avoids the need to cd back.

This catches if cd fails and also avoid the need to cd .. back.

Note that A && B || C is not if-then-else. C may run when A is true.

An outstanding bug in GHC pre-8 causes haddock comments on GADT constructors to fail, which in turn prevents the bootstrapping process from finishing. This works around it by skipping haddocks for hackage-security.

Fixes #3139. Fixes #3133.

Otherwise the build will fail on GHC 8. See #3133.

See #3133.

Needed because cabal-install no longer compiles against Cabal-1.23.1 snapshot
that came with GHC 8.

In 46584a2f I've accidentally put the hashable version string on a
separate line, causing the shell to try to execute the command
"1.2.4.0".  Fix it by removing the line.

Since 1e1d82b8, hashable is needed.  Adapt bootstrap.sh accordingly.
