[Qemu-devel] [PATCH] Fix signal.c warning

[Nathan Froyd <froydnj@codesourcery.com>]

This patch fixes:

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

by making the appropriate functions static.
