libbsd fails to link on i386

[Jan.Sommer at dlr.de]

Hi Joel,



Sorry for the long delay.

I tried to reproduce the error locally. For me building rtems and rtems-libbsd 
master for pc386 and pc686 works.

I get some undefined references for the 6-freebsd-12 branch though.

Which branch of rtems-libbsd did you use?



Best regards,



    Jan

Hi Joel,



I remember I spent some time fiddling with the bus.h include order.

I can try to have a look at it some time next week.



Best regards,

Hi



I think the wrong bus.h must be being included somewhere. These are static 
inline methods on the i386. Hopefully a simple patch for someone who knows 
what to do:
