Sadly not,
+no-machine:
+ rm -f ${.CURDIR}/../../ficl/machine
.. this is definitely bogus no matter what. This attempts to modify
the source tree which may be read only, and should never even have a
"machine->..." symlink in it to remove in the first place.
I see sys/boot/userboot/ficl/Makefile has commented out the code that
sets up the ./machine links in its ${.OBJDIR} and there's -I paths all
over the place so my guess is that it's picking up some of the i386
machine links rather than setting up its own. You probably need to
look at the userboot/ficl/Makefile code and make sure its setting up
the correct links rather than accidently using one belonging to
something else.
Or your source tree is contaminated somehow with a machine-> link
somewhere that it isn't supposed to be.
