I've put mkSOName in HscTypes for now; I'm not sure what the best place
for it is.

This required various build system changes to get the build to go
through.

In the inplace shell wrappers, we set LD_LIBRARY_PATH to allow programs
to find their libraries. In the future, we might change the inplace tree
to be the same shape as an installed tree instead. However, this would
mean changing the way we do installation, as currently we use cabal's
installation methods to install the libraries, but that only works if
the libraries are under libraries/foo/dist-install/build/..., rather
than in inplace/lib/...

We used to use a list lookup that couldn't fail. Now we just use
functions.

There were 3 overlapping entries for WayPar; I've commented out the ones
that were shadowed for now.

-rtsopts has no effect with -shared, so we should emit a warning.  See
 #5373 and #7177.

Supresses an ugly warning from gcc 4.6+ saying this is a C/ObjC flag
only.

Related to #4862

They were getting baked into Config.hs before.

Hopefully I've kept the logic the same, and we now generate warnings if
the user does -fno-PIC but we ignore them (e.g. because they're on OS X
amd64).

We now handle the preprocessor options the same way as the gcc options
(picCCOpts).

We were pointlessly going from String to SDoc and back again

A side-effect is that we can no longer use the LogAction in
defaultErrorHandler, as we don't have DynFlags at that point.
But all that defaultErrorHandler did is to print Strings as
SevFatal, so now it takes a 'FatalMessager' instead.

This patch enhances Platform's ArchARM to include ARM ABI value. It also
tweaks configure machinery to detect hard-float ABI and to set it wherever
needed. Finally when hard-float ABI is in use, pass appropriate compiler
option to the LLVM's llc. Fixes #5914.

createDirectoryHierarchy consisted of an existence test followed by
createDirectory, which failed if that directory was creted just after
the test. createDirectoryifMissing does not have this problem.

Fixes gas errors when -g is enabled:

Error: can't resolve `.debug-ghc-link-info' {.debug-ghc-link-info section} - `.Ltext0' {.text section}

We no longer have many separate, clashing getDynFlags functions

I've given each GhcMonad its own HasDynFlags instance, rather than
using UndecidableInstances to make a GhcMonad m => HasDynFlags m
instance.

We now require GHC >= 7.0, which has the behaviour we want.

Based on a patch from Arnaud Degroote <degroote@NetBSD.org> in
trac #5480.

LLVM doesn't support the OS X system assembler anymore so we must use
their assembler through clang. Also improved error messages when various
LLVM tools can't be run.

Currently it is appearing on stderr, whereas the rest of the messages
from --make go to stdout, this change fixes that.
