Helper Makefile for testing gcc toolchains using the gcc-testsuite

 ==================================================================

 Requirements

 ------------

 * DejaGnu 'runtest' v1.4.4+

 * Make v3.81+

 * wget

 Configuration

 -------------

 Edit default.cfg to reflect your toolchain and target configuration.

 Alternatively, override configuration variables on the command line.

 Available config variables:

 DG_GCC_VERSION

 DG_GCC_URL

 DG_TOOLNAME

 DG_TARGET

 DG_TARGET_HOSTNAME

 DG_TARGET_USERNAME

 DG_C_TESTS

 DG_CPP_TESTS

 DG_TOOLCHAIN_DIR

 DG_SRC_DIR

 Run examples

 ------------

 The first two examples require a networked target with ssh access and automatic

 ssh login (see section below). Target SW should be compiled with the toolchain 

 to be tested.

 Run default gcc compile/execution tests:

 $ make DG_TOOLNAME=gcc DG_TARGET_HOSTNAME=192.168.17.93 DG_TARGET_USERNAME=root

 Run default g++ compile/execution tests:

 $ make DG_TOOLNAME=g++ DG_TARGET_HOSTNAME=192.168.17.93 DG_TARGET_USERNAME=root

 Run selected gcc compile only tests (no target required):

 $ make DG_TOOLNAME=gcc DG_C_TESTS="compile.exp noncompile.exp" 

 SSH automatic login configuration example

 -----------------------------------------

 On host do: 

 ssh-keygen -t rsa (then simply press enter thru all steps)

 scp ~/.ssh/id_rsa.pub <username>@<target IP>:~/

 On target do:

 cd ~

 mkdir .ssh

 cat id_rsa.pub >> .ssh/authorized_keys

 rm id_rsa.pub

 Now automatic ssh login should work - test by doing a simple ssh session to target.

 Note: The procedure might be slightly different for your particular target.
