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
code.
This patch differs from the previous version
<https://sourceware.org/ml/libc-alpha/2015-10/msg00705.html>
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.
