 i think this is caused by this rule:
 
 usr.bin/backend/Makefile:
 
 # genattrtab has three output files
 # XXX fix me
 insn-attrtab.c insn-dfatab.c insn-latencytab.c: genattrtab ${G_md_file} in=
 sn-conditions.md
 	${_MKTARGET_CREATE}
 	./genattrtab ${G_md_file} insn-conditions.md -Ainsn-attrtab.c -Dinsn-dfat=
 ab.c -Linsn-latencytab.c
 CLEANFILES+=3D    insn-attrtab.c insn-dfatab.c insn-latencytab.c
 
 just judging by what file fails most(all?) of the time.
