The existing code supports reading multiple preferred-versions files in
the 00-index.tar and merging them. However it doesn't do it quite right
when the same file is updated, it merged them instead of the later one
overriding the first.

This should make no difference right now because the 00-index.tar
typically only contains a single preferred-versions file, with no
updates.

Implement offline mode for the 'install' command.

Improve a number of ghc-options checks

Currently there are no checks that need to be specific to one of them.
Both sets of options get used in distributed packages.

And extend it to cover other similar variants. People often put it in to
help them profile *this* package, but it causes problems for profiling
other packages. The -fprof-auto-exported is arguably ok though.

The -threaded flag really makes no difference for libraries, it's a
link-time option only.

Improve the package description check for -Werror and similar flags so
that they are allowed so long as they're not enabled by default. We
check the conditions that they're guarded by to make sure they're always
false (given the default values of the manual flags). Also extend the
error messages to explain how to use these flags with conditionals.

Rewrite linker check to avoid grepping "ld"s.

I was the one who introduced that bit, and it seems like well may have caused more trouble than it helped... so, sorry :(

Anyway, clang has since then grown the ability to `-print-prog-name`, so I've done away with all that grepping through -### stuff.
@creswick @23Skidoo, could you see if this works for you?
