Build fails after rebasing attempt

[Darius Mihai]

Hi all,

After attempting to rebase the bhyve on ARM project using the latest
master commits, the building process fails with the following
error(s):
--- all_subdir_vmm ---
make[4]: Graph cycles through `hyp_assym.h'
make[4]: Graph cycles through `hyp_genassym.o'

*** [all_subdir_vmm] Error code 1

Since the buld did not fail prior to rebasing the code, I am not
entirely sure how I should fix this. If anyone wishes to take a look
at the code, the error seems to be thrown when trying to build the vmm
kernel object (sources are in the directory at [1]) for the guest
operating system (configuration file is at [2] and dts unde the
directory at [3] - I am aware that the location changed, but the error
is not caused by a missing file in the configuration).

The configuration for the make buildkernel command is
TARGET_ARCH=armv6, TARGET=arm, MAKEOBJDIRPREFIX=$HOME/freebsd-obj/;
KERNCONF=FVP_VE_CORTEX_A15x1_GUEST is sent as a command line
parameter.
