gdbserver: remove support for Blackfin
This port has been unmaintained for years and the upstream Linux kernel does not support this architecture anymore, remove it. gdbserver/ChangeLog: * Makefile.in (SFILES): Remove linux-bfin-low.c. * configure.srv: Remove bfin case. * linux-bfin-low.cc: Remove. * linux-low.cc: Remove BFIN-conditional code. Change-Id: I846310d15e6386118ec7eabb1b87e647174560fb
