José Fonseca b6956aef74 scons: Search only for mingw-w64 cross-compilers. 
Some distros still ship the non-mingw-w64 cross-compilers, but they are
can't build Mesa properly, as Jakob pointed out.

José Fonseca 8cabc7be1d scons: Don't force stabs debug format for Mingw. 
- recent gdb handles DWARF fine (tested both with version
  7.1.90.20100730 from mingw-w64 project, and 7.5-1 from mingw project)

- http://people.freedesktop.org/~jrfonseca/bfdhelp/ was updated to
  handle DWARF

- stabs requires ugly hacks to prevent compilation failures

- mixing stabs/dwarf prevents proper backtraces (which is inevitable,
  given that the MinGW C runtime is pre-built with DWARF)

For example, without this change I get:

  (gdb) bt
  #0  _wassert (_Message=0xf925060 L"Num < NumOperands && \"Invalid child # of SDNode!\"",
      _File=0xf60b488 L"llvm/include/llvm/CodeGen/SelectionDAGNodes.h", _Line=534)

José Fonseca 191428ccb8 scons: Prefer x86_64-w64-mingw32- prefix. 
This allows to use mingw-w64 binaries on debian systems which already

Brian Paul cdb7396390 scons: don't compile some files with -gstabs if using mingw32 
Compiling some (large) files with i686-pc-mingw32-gcc 4.2.2 (at least)
and the -gstabs option triggers a compiler error.  Use this work-around
to simply compile the effected files without -gstabs.

José Fonseca 82e79e93ac scons: Eliminate libgcc_s_sjlj-1.dll dependency 
Certain mingw32 cross compilers (e.g. RedHat's) defaults to use DLL gcc
runtime.

Given the main deliverable from this project are self-contained drivers,
which are loaded by any application, this dependency can cause havoc.
