This commit adds make rules to build %.o and %.os files from %.i8
Infinity note source code.

In order to ensure the correct preprocessor and assembler are used
for cross-builds the compilation is done in three stages.  The target
preprocessor specified at ./configure time is used to preprocess the
%.i8 source; I8C consumes this preprocessed source and emits assembly
language; and finally the target assembler specified at ./configure
time is used to assemble the generated assembly language into object

This patch differs from the previous version
in the following ways:

 * The infinity-%.S => infinity-%.o and infinity-%.os rules are
   no longer necessary and have been removed.

 * "-include sysdep.h" is passed to I8C to ensure the correct
   assembler directives for ARM are included.
