Hi!
These are patches submitted by Andreas Tobler to get qemu working on
FreeBSD/ppc hosts. There is one other patch to ppc.ld that's needed
because of FreeBSD's older binutils that probably should stay
FreeBSD-specific, here is the link to it in FreeBSD ports:
http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/qemu-devel/files/patch-ppc.ld
1. Add FreeBSD/ppc host ppc_init_cacheline_sizes() implementation.
2. Add FreeBSD/ppc host ucontext definitions.
3. Add FreeBSD/ppc host TCG_TARGET_CALL_{ALIGN_ARGS,STACK_OFFSET} definitions.
