probs building for fbsd smp

[Richard Nyberg]

To build arla-0.35.4 for FreeBSD 4.3 with SMP kernel it seems that you 
have to define APIC_IO in addition SMP.

When APIC_IO is defined arla builds fine, when it's not the build breaks
like this:
--------------------------------
gcc -c  -DHAVE_CONFIG_H -I. -I.  -I../../include -I./../../include  
-I./../include  -I/pkg/krb4/1.0.8/include -DXFS_DEBUG -DINET6 -g  -Wall 
-Wmissing-prototypes -Wpointer-arith -Wbad-function-cast 
-Wmissing-declarations -Wnested-externs -O  -DSMP -D__SMP__ -DKERNEL 
-D_KERNEL -DVFS_KLD -DKLD_MODULE -I/sys/arch -I/sys -I. -Wno-unused
