[Xen-devel] RE: xen/ia64 crosscompile

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

I finally got around to trying your patch. It seems to work fine for
cross-compiling but it doesn't work native (on an ia64).  It appears
that CC gets set to CROSS_COMPILE, which wreaks havoc.

I can get around this problem by surrounding the setting
of CROSS_COMPILE with ifneq ($(COMPILE_ARCH),$(TARGET_ARCH))

Will this do?
