gcc-4.6.0: Backport FSF 4.6 branch patches
This is set of bugfixes that has been done on
FSF gcc-4_2-branch since 4.6.0 was released
They will roll into 4.6.1 release once that
happens in coming approx 6 months time then
we can simply remove them thats the reason
so use a separate .inc file to define the
SRC_URI additions
