Yes it does. It's still not the clean tree so I'll try to retest without
ccache.
I don't think ccache is really involved because as I said before when I
issue the same command from /usr/obj/usr/src/libexec/bootpd it succeeds.
/etc/make.conf follows:
CPUTYPE?=native
INSTALL:=install -C
WITHOUT_NOUVEAU:=yes
KERNCONF?=MINIMAL #GENERIC
NO_CLEAN:=yes
.if (!empty(.CURDIR:M/usr/src*) || !empty(.CURDIR:M/usr/obj*))
