[OE-core] Build issue of nativesdk toolchain

[Luo Zhenhua-B19537]

When I build nativesdk toolchain with recent poky + meta-fsl-ppc + FSL SDK specific layers, build issue similar to error-1 happens. This issue might appear for different gcc related package during different trial, e.g. libgcc, gcc, gcc-cross-initial, gcc-crosssdk, etc. 

When I revert http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=9bfd92243eced921f166d84b5a72d6f774e13413, error-1 build issue goes away, error-2 appears, error-2 also can't be reproduced every time. Does anyone ever meet the similar build issue and any comment on the build error?

[Error-1 logs]:
