From 86aa4d8d11cbe49d81ce0a054570d6e5d59f372e Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Tue, 31 May 2016 23:01:36 +0200 Subject: [PATCH] gdb: enable simulator support for host build Add an option to enable GDB simulator support, so it can be used to test some no-MMU systems. Newer GDB Blackfin Simulator need a workaround for in-tree compile. It doesn't break for older Buildroot supported GDB Blackfin Simulator.
