Package gcc.unwind and gcc.gthreads
Debug emission cleanups
Fix cross-native compilers

A cross-native compiler is a native compiler (host==target) which was
built on a different architecture (build != (host == target)).

This is not a cross compiler and should be handled just like a normal
native compiler.

More importantly: Paths must be in sync with gcc/d/Make-lang.in
otherwise
the compiler doesn't find the import files.
Fix ICE on Windows/MinGW hosts

The microsoft runtime doesn't support the "%z" format specifier.

Fixup commit for 'Fix cross-native compilers'

$host and $target in libphobos are not the same as the compilers host
and target. Read the pkgvars file to get the correct information.
Set template as local if the instantianting module is being emitted
Assume the prefix length for a symbol fits into an unsigned int
ChangeLog rotate
[ARM] Implement ASM for test-suite tests
[ARM] Port remaining test-suite tests

* test42: Ported to standard varargs
* test4, template1.d: Add missing constants for ARM
Skip evaluation order tests on non X86 architectures

See GDC issue #8. Skipping these tests allows running the
remaining tests in arrayop.d
Add support for adjusting the test-suite timeouts
[ARM] Implement math-related stuff in phobos
[ARM] Implement parse!real for systems with 64bit reals

and unittest fixes.
[ARM] UNWIND_PAD definition is wrong for EABI unwinder
[ARM] Fix phobos unit tests
