Comment (by kgardas):

 with new build system smp enabled build of pc686 fails. Linkage of samples
 fails with
 {{{

 that's due to fact this part of Makefile based build was not translated to
 the new build system:
 {{{
 appcpustart.$(OBJEXT): ../../../../../../bsps/i386/pc386/start/startAP.S
         $(CPPASCOMPILE) $(AM_CPPFLAGS) -o $@ -c $<

 appstart.$(OBJEXT): appcpustart.$(OBJEXT)
         $(LD) -N  \
             -Ttext 0x70000 -e app_processor_start -nostdlib \
             -o appstart_tmp.exe $<
         $(OBJCOPY) -O binary appstart_tmp.exe appstart.bin
         $(OBJCOPY) -I binary -O elf32-i386 -B i386 appstart.bin $@
 }}}
 besides this there is also error in files (getcpuid.c seems to be gone,
 bspsmp.c needs to be there:

 {{{

 unfortunately so far I struggle with translating this to waf, probably
 should look for some waf doc or so. E.g. linking steps of appcpustart.o
 into appstart.o is what makes me trouble. Also I'm not able to find out
 how rtemsbsp lib is linked and its dependency specified...
