There's a problem with the newer linux system include files for
building the linux host portions of the cross compiler.
(in /usr/include)
Specifically, in unistd.h, there are declarations for llseek which
freak out the cross compiler build; and in bytesex.h, which #error's out
if the target processor code is being built for isn't explicitly
declared,
the H8 isn't.

Unified diff's which can be used with patch to fix those two files for
building an h8300 compiler follow:
