The SPARC code in linux-user/signal.c defines a set of
MC_* constants. On some SPARC hosts these are also defined
by sys/ucontext.h, resulting in build failures:
linux-user/signal.c:2786:0: error: "MC_NGREG" redefined [-Werror]
#define MC_NGREG 19
In file included from /usr/include/signal.h:302:0,
from include/qemu/osdep.h:86,
from linux-user/signal.c:19:
/usr/include/sparc64-linux-gnu/sys/ucontext.h:59:0: note: this is the location of the previous definition
# define MC_NGREG __MC_NGREG
Rename all these constants to SPARC_MC_* to avoid the clash.
