This patch fixes:

linux-user/signal.c:1403: warning: no previous prototype for 'do_sigreturn_v1'
linux-user/signal.c:1473: warning: no previous prototype for 'do_sigreturn_v2'
linux-user/signal.c:1511: warning: no previous prototype for 'do_rt_sigreturn_v1'
linux-user/signal.c:1552: warning: no previous prototype for 'do_rt_sigreturn_v2'

by making the appropriate functions static.
