Debian-9.5/amd64.
But building hello.mo with i386-elf-gcc (5.5.0) cross compiler on
OpenBSD-6.3/amd64, undefined reference to 'rt_kprintf' error occurs.
To avoid this error, "compile and link" process needs to be divided to
simply "compile" and "link".
On Debian-9.5, both previous and current method produces same hello.mo.
We have to improve disk image creation (Linux dependent),
this is a future homework.
1. upddate kernel module to support i386
2. update libdl to support open *.so by absolute path
3. new test case bsp/x86/src/hello.c to test i386 module feature
