cross-canadian: Handle powerpc linux verses linux-gnuspe

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]

Hi,

I believe this commit is the cause of some problems I'm seeing with ppc SDK toolchain tarballs on poky master.

1. Looks like the relocation scripts fails for environments:

~/tests/poky [master]

$ cat /opt/oel/2014-01-01/environment-setup-ppce500v2-oel-linux | grep "#"
export SDKTARGETSYSROOT=##SDKTARGETSYSROOT##

~/tests/poky [master]

$ cat /opt/oel/2014-01-01/environment-setup-ppce500v2-oel-linux-gnuspe | grep "#"

2. SDK gnuspe compiler does not allow -mabi=spe ABIEXTENSION is zeroed both for linux-gnuspe and linux

3. Compiler can't create executables.
I think this is due to libgcc_s.so from the SDK target sysroot is in mabi=spe.

4. -mspe is included in CC var for both linux and gnuspe.

cat /opt/oel/2014-01-01/environment-setup-ppce500v2-oel-linux | grep mabi
export CC="powerpc-oel-linux-gcc -m32 -mcpu=8548 -mabi=spe -mspe -mfloat-gprs=double --sysroot=$SDKTARGETSYSROOT" export CXX="powerpc-oel-linux-g++ -m32 -mcpu=8548 -mabi=spe -mspe -mfloat-gprs=double --sysroot=$SDKTARGETSYSROOT" export CPP="powerpc-oel-linux-gcc -E -m32 -mcpu=8548 -mabi=spe -mspe -mfloat-gprs=double --sysroot=$SDKTARGETSYSROOT"

Seems to work in dora though,

Any thoughts on this ?

Br,
David
