ARCH=i386, A kernel is 2.4.26 with a patch from tccboot.iso
https://googledrive.com/host/0B35PjbLHNzyqbklHTUd6ampvd0E (this is
tcc-kernel-2.4.26.tar.bz2 in my GoogleDrive) contain all to build this
kernel. A minimal kernel config is used. But this kernel boots using a
ramdisk and there is a bash prompt. Mostly this is tccboot.iso which
use a kernel compiled by the current tcc.

PS: a "build" executable is for i386. A gcc-2.9.95 can compile this
kernel. A new gcc compilers can not compile this version of the
kernel. I planning to compile a 2.4.37 kernel by tcc (with the same
config).

Excelent, thanks!
