arch/xtensa: add definitions for the Xtensa overlay
Currently, we have four packages that need to use the Xtensa overlay:
binutils, gcc-initial, gcc-final and gdb. However, they all use three
different ways to check for, and use the overlay. Furthermore, two of
them define the same variable: XTENSA_CORE_NAME is defined both by
binutils and gdb
In order to sanitise that, have the Xtensa architecture export the
appropriate variables: the name of the core and the path to the overlay
tarball. Packages can then check and use those variables.
