Architecture of host must be compitable architecture with target.

Let's make exception handling for different architecture between
host pc and target board during build-time.

V3:
- Simplify the existing 'if' statement

V2:
- Added $HostArch variable to handle the required architectures.

V1:
- Handle "time ./build.sh arm debug clean verbose" command
in case that generate only mscorlib.dll for Linux/ARM as well as the
existing case of if [ $__CrossBuild != 1 ]

In this case, we need to add additional if statements because the
architecture of host pc must be same architecture with target.
