clang differs subtly when it comes to sysroot support as compared to gcc
where the gcc driver is compiled with lot of the paths and information
clang is not, nativesdk sysroot is tuned to where gcc expects it, this
does not work well for clang, since clang looks for all
headers/libraries/compiler-runtime under same sysroot whereas gcc has
diffrent understanding of sysroot for target and where it expects gcc
headers and other tools needed for compilation. Anyway short story is
that we create symlinks into directories for include/ and usr/lib so
clang is happy and it does not affect gcc crosssdk
