Merge the canadian branch to default.
Now the preliminray support for canadian-crosses is done,
merge to default. The few remaining quirks, if any, will
be resolved on mainstream.
1 This is a somewhat ordered TODO list:
5 - update versions for every tools...
12 - add newlib (for enhanced bare metal)
13 - may need heavy tweaks and bends in gcc.sh
14 - try to make it generic, will help for uClibc++
15 - check whether it supports running under uClinux
20 - Cygwin target (needs newlib)
21 - so we can complie for Windows/Cygwin
24 - so we can compile for Windows/Win32
27 - so we can run natively under Windows/Win32 (without requiring Cygwin)
30 - see: http://sourceware.org/ml/crossgcc/2009-05/msg00022.html
