After looking around in all ends of OE-core it shows up that this
error is caused by binutils.inc.
Finding ar would be no problem itself, but if the binary is not
installed or gets deleted after building binutils-native it is
impossible to locate it.

In binutils.inc do_install:
rm ${D}${bindir}/ar ${D}${bindir}/strings

Well I still wonder why my target sysroot has ar if it gets deleted here...

Anyone knows why ar is being removed in do_install?
