When building only the leon3 machine, we get this link failure:
/usr/bin/ld: target_sparc_win_helper.c.o: in function `cpu_put_psr':
target/sparc/win_helper.c:91: undefined reference to `cpu_check_irqs'
This is because cpu_check_irqs() is defined in hw/sparc/sun4m.c,
which is only built if the base sun4m machines are built (with
the CONFIG_SUN4M selector).
Fix by moving cpu_check_irqs() out of hw/sparc/sun4m.c and build
it unconditionally.
