[Qemu-devel] [RISU v2 01/11] Makefile: undefine the arch name symbol

[Jan Bobek]

At least GCC defines the symbol "i386" to 1 to signal the target
platform. We need to use "i386" as an undefined symbol in order to
correctly include risu_reginfo_i386.h from risu.h. Add an -U option to
the build command to make sure the symbol remains undefined.
