[PATCH v4 03/44] gdbserver: allow configuring for a heterogeneous target

[Markus Metzger <markus.t.metzger@intel.com>]

From: Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>

gdbserver's configure.srv requires host and target systems to be the
same.  This prevents building gdbserver for when a target other than
the native CPU is to be debugged, e.g.  a heterogeneous system with an
Intel GPU where we want to debug the GPU.

Allow for such a combination by special-casing the Intel GPU target to
preserve the existing behavior for other cases.
