[PATCH v4 0/3] [5-freebsd-12] Fix compilation for i386

[Jan Sommer]

This is the  backport for the 5-freebsd-12 branch to make rtems-libbsd compile for i386 again:
- It also introduces path-mappings to waf_libbsd.py as introduced here:
https://lists.rtems.org/pipermail/devel/2020-February/057457.html

Changes compared to v3:
- iflib.c: Properly deactivate usage of ifc_cpus 
- subr_gtaskqueue.c: Deactivate BSD_ASSERT for i386 (will open a
  discussion for that)
- Could successfully run network tests (e.g. dhcpcd0x.exe on hardware)

Changes compared to v2:
- callout.h: Change the callout_reset_on macro
- iflib.c: Do not use different callout* macro, but use the changed one

Happy Easter,

   Jan
