Omit this check because this check is not really necessary and it is
dealing more harms than goods to ARM boards.
While body load address is configurable, it is not quite possible to fix
all the build scripts and runtime scripts to carry this address; so in
reality all scripts use the default body load address.
The problem is, this default address is not friendly to ARM boards, and
it virtually makes this check fails on ARM boards.
