Subject: [PATCH 1/2] codafs: Fix build using bare-metal toolchain

The kernel is self-contained project and can be built with bare-metal
toolchain. But bare-metal toolchain doesn't define u_quad_t type.
Because of this codafs build fails when building with bare-metal
toolchain. This patch fixes it by defining u_quad_t type in case when
non-Linux toolchain is used.
