[OE-core] [PATCH] cross-canadian: Handle powerpc linux verses linux-gnuspe

[Richard Purdie]

PowerPC toolchains can use the OS "linux" or "linux-gnuspe". This
patch links them together so the one cross-canadian toolchain can support
both.

GCC_FOR_TARGET is set for the GCC recipe as otherwise configure
can pick up an incorrect value.

[YOCTO #5354]
