The latest gcc 10.x changes the default to '-fno-common'. This causes a couple
of build failures in ACRN. This patch changes the default behaviour to
'-fcommon' for the 'acrnprobe' tool and fixes the 'hv_prebuild' codebase.
More details on that change can be found here:

HV_SUPPORTED_MAX_CLOS:
This value represents the maximum CLOS that is allowed by ACRN hypervisor.
This value is set to be least common Max CLOS (CPUID.(EAX=0x10,ECX=ResID):EDX[15:0])
among all supported RDT resources in the platform. In other words, it is
min(maximum CLOS of L2, L3 and MBA). This is done in order to have consistent
CLOS allocations between all the RDT resources.

add an IVSHMEM regoin and the related configuration parameters in
hybrid_rt scenario on whl-ipc-i5. The size of the shared memory is
2M, and it is used for the communication between VM0 and VM2.
v6: rename shm name; remove unnecessary MACROs.
v7: rename MACRO for shm name; add unassigned vbdf for post-launched
VMs.

This patch will move the VM configuration check to pre-build stage,
a test program will do the check for pre-defined VM configuration
data before making hypervisor binary. If test failed, the make
process will be aborted. So once the hypervisor binary is built
successfully or start to run, it means the VM configuration has
been sanitized.
The patch did not add any new VM configuration check function,
it just port the original sanitize_vm_config() function from cpu.c
to static_checks.c with below change:
1. remove runtime rdt detection for clos check;
2. replace pr_err() from logmsg.h with printf() from stdio.h;
3. replace runtime call get_pcpu_nums() in ALL_CPUS_MASK macro
with static defined MAX_PCPU_NUM;
4. remove cpu_affinity check since pre-launched VM might share
pcpu with SOS VM;
The BOARD/SCENARIO parameter check and configuration folder check is
also moved to prebuild Makefile.
