Thanks Ian, and attached is the patch to do that change. I'm not expert
in Makefile, so feel free to pin me for better solution. :-)
=============================
Libxc is the part coupling with platform context most tightly,
with some files which should be made arch dependent. Obvious example is
xc_***_build.c, which should behave upon vcpu_guest_context_t defined by
different platform.
Following patch is trying to move those files into arch
dependent directory. I only addressed 7 files by far, because
compilation succeeds on IPF simply after solving them. Since there's no
distinct boundary between them and other files, I'm lazy to add another
Makefile under arch-dep directory. Also no change to compile option
since they works fine on x86 and IPF currentlys.
To reduce the size of patch, a trick is used to move files when
first compilation. After that, you can simply remove 8 lines leading by
"TEMP" comment. IPF related changes will be sent to Dan later.
