No my script doesn’t use `-r BUILD_TREE` option.
I’m using the arm-linux-androideabi-gcc compiler from android’s ndk
toolchain, so I would like to assume that it’s linker would
automatically search through the required android kernel’s libraries
and headers and find the required definitions.
This is a strange behaviour.

Any possible environment variables I need to set, for the compiler to
look at the correct place?
