BSD compatibility is not optional for the kernel to build, however
platform dependent portion of this configuration, machine_resource_init(),
which is called by nexus_init() is implemented only in the platform
specific library for HiSilicon chips (libhi35xx_bsp.a).
Workaround lack of this library, so that the kernel can be built
for other platforms as well, by excluding it from the compilation.

This change should be removed as soon as the appropriate function
is implemented for other platforms.

During LiteOS consolidation, system_init.o object that contains
SystemInit() doesn't exist yet as it is being built later
and linked in ./vendor directory when OHOS_Image is created.
This is not the case when building for HiSilicon platforms as
SystemInit is provided for them in precompiled libraries.

Workaround this issue by creating "weak" function in LiteOS
that will be replaced by the "strong" symbol from ./vendor
in linking phase of the OHOS_Image.
