[OE-core] [PATCH] gdb-cross: Adjust ${datadir} to avoid file conflicts in sysroot

[Phil Blundell]

GDB wants to install a bunch of files in ${datadir}/gdb/python/gdb
and ${datadir}/gdb/syscalls.  These pathnames are invariant with
TARGET_ARCH which means that if you build gdb multiple times for
different targets they will all try to write to the same location
and you get a lot of warning spew about manifest conflicts.

Prevent this by factoring the target specification into ${datadir}
so that different copies of GDB install their files into different
paths.
