[OE-core] Build issue of nativesdk toolchain

[Luo Zhenhua-B19537]

FSL gcc source is used for following gcc variants, and other gcc variants use Yocto default source. "+fsl" suffix is appended into PV in below gcc recipes. My understanding is that below gcc variants should use a different build folder with gcc-crosssdk, am I misunderstanding something? 

I might need to unify the source for all gcc variants if Yocto doesn't support above scenario.  

Gcc variants with FSL source: 
gcc_4.7.bbappend        gcc-cross-canadian_4.7.bbappend  gcc-fsl.inc               libgcc_4.7.bbappend
gcc-cross_4.7.bbappend  gcc-cross-initial_4.7.bbappend   gcc-runtime_4.7.bbappend

$ cat gcc-fsl.inc 
PV = "4.7.2+fsl"

BINV = "4.7.2"

SRCREV = "c88a2f851197a103296175e0a7a1cb94ab91bcc3"

SRC_URI = "git://git.am.freescale.net/gitolite/sdk/gcc.git;destsuffix=gcc-${PV} \
        file://optional_libstdc.patch \
        file://use-defaults.h-and-t-oe-in-B.patch \
        file://GLIBC_DYNAMIC_LINKER.patch \
"

FILESEXTRAPATHS_prepend := "${THISDIR}/files:" 

Below is the content of the bbappend: 
require gcc-fsl.inc


Best Regards,

Zhenhua
