-Intro
------
-
-You can compile AbaOS from a 32-bit host or chroot (e.g. Arch32 chroot).
-But you have to be extremly careful that nothing ceeps into the kernel
-from the host system.
-
-You can also create a cross-compilation environment. Now, we don't need
-a full fledged chain, linker and C compiler is enough. AbaOs has a small
-integrated C library which is sufficient to build the kernel.

-Clang is easy, usually it already supports common targets. Just
-for the kernel we need a i486 linker from binutils:
