if we want to be able to build per machine then we have to add put the
tools under MACHINE dir in native sysroot
but subfamilies can be differentiated like arm5t, armv5teb, armv7 etc
thats how far compiler/toolchains can
differentiate. There is no problem with two  different architectures
e.g. mips, arm
