* Set a null-ABI for toolchains where detection of ABI failed: This
  allows the user to select any tool chain.

* Warn if ABI detection fails by showing a message in the Qt version
  setup dialog

* Do not override the mkspec if the Qt version has a null ABI only:
  We (have to) trust the user to know what he is doing in that case.

* GCC: Add version information to GCC tool chain and use it to select
  the mkspec on Mac.

* GCC: Do not override mkspec if we do a cross-compile
  (and actually detect that).

* GCC: Leave out -32 or -64 from mkspec if the compiler binaries ABI
  matches the target ABI.

* Linux-generic is compatible with all other linuxes (both ways)
  The targets themselves do additional filtering and will remove
  anything that does not work for them anyway.

This fixes all the buttons staying in disabled mode after an (unsuccessful)
compilation. Problem was that in the end, the finished() call informed
the option page that the build was over, while the updateQtVersions()
call updated the UI. The patch fixes the order, but also updates the UI
as reaction to the finished call, because relying on the delivery order of
two independent signals via Qt::QueuedConnection is fragile per se.

Despite of '-k' passed to make, the 'all' target might still fail prematurely
because make doesn't forward the '-k' to sbs. Anyway, now that we
know the exact toolchain we can do better and only compile the
targets that fit to the toolchain.

If not Symbian, use the 'all' target everywhere, which ensures
we're both compiling debug and release versions of all helpers.
