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.

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
