unicore32 builds fail with

arch/unicore32/kernel/signal.c: In function ‘setup_frame’:
arch/unicore32/kernel/signal.c:257: error:
‘usig’ undeclared (first use in this function)
arch/unicore32/kernel/signal.c:279: error:
‘usig’ undeclared (first use in this function)
arch/unicore32/kernel/signal.c: In function ‘handle_signal’:
arch/unicore32/kernel/signal.c:306: warning: unused variable ‘tsk’
arch/unicore32/kernel/signal.c: In function ‘do_signal’:
arch/unicore32/kernel/signal.c:376: error:
implicit declaration of function ‘get_signsl’
make[1]: *** [arch/unicore32/kernel/signal.o] Error 1
make: *** [arch/unicore32/kernel/signal.o] Error 2

Bisect points to commit 649671c90eaf ("unicore32: Use get_signal()
signal_setup_done()").

This code never even compiled. Reverting the patch does not work,
since previously used functions no longer exist, so try to fix it up.
Compile tested only.
