[OE-core] [PATCH 6/6 V3] gcc-cross-canadian: share work directories

[Robert Yang]

We had made gcc' configure to use the hacked defaults.h and t-oe in
${B}/gcc for gcc-cross, gcc-cross-canadian doesn't need the hacked
defatuls.h or t-oe, but we need make their source compatible, so:

1) copy ${S}/gcc/deafults.h(which is the original one with no change) to
   ${B}/gcc, it is the same as use the one in ${S}/gcc.

2) gcc-cross-canadian doesn't need the t-oe, so touch a empty t-oe for
   it, this doesn't change any behaviour of gcc-cross-canadian.
