[OE-core] GCC 4.9 and Morty

[Lee, Yong]

Thank you.
I switched to internal toolchain and building GCC 5.4 (included in meta) is complete and is onto glibc.

In summary, TI SDK appears to be broken as the none-default GCC version included in their package (ie. Linaro 4.9 and Linaro 5.2) fails to build.

Your changes look fine.

you might have to bug your SDK provider for gcc 4.9 build issue
