Well, Usually distro's insert their identify via setting TARGET_VENDOR
and let the build system compose the tuples
and those tuples are represented by ${TARGET|HOST|BUILD}_SYS which are
then used to componse equivalent _PREFIX variables.
for cross tools like gcc etc. not only target but host prefix is also
important. So if you override just target it still uses a mismatched
tuple and hence the errors you are seeing. I wonder if you override
TARGET_SYS and HOST_SYS it might make you go further.
