gdb/testsuite: add a new check-all-boards target
The make-check-all.sh script (gdb/testsuite/make-check-all.sh) is
great, it makes it super easy to run some test(s) using all the
available board files.
This commit aims to make this script even easier to access by adding a
check-all-boards target to the GDB Makefile. This new target checks
for (and requires) a number of environment variables, so the target
should be used like this:
make check-all-boards GDB_TARGET_USERNAME=remote-target \
GDB_HOST_USERNAME=remote-host \
TESTS="gdb.base/break.exp"
Where GDB_TARGET_USERNAME and GDB_HOST_USERNAME are the user names
that should be passed to the make-check-all.sh --target-user and
--host-user command line options respectively.
My personal intention is to set these variables in my environment, so
all I'll need to do is:
make check-all-boards TESTS="gdb.base/break.exp"
The make rule always passes --keep-results to the make-check-all.sh
script, as I find that the most useful. It's super frustrating to run
the tests and realise you forgot that option and the results have been
discarded.

+
+These settings are only used with the check-all-boards target, and
+should be the usernames of two separate users on the local machine,
+both of which the current user can ssh to without a password.
+
+These users will be used by board files that simulate remote targets
+by switching to a different user on the same machine. These users
+will have random files copied into their $HOME directories, so it is a
+good idea to setup new users just for this purpose.
+
+Testing All Simple Boards
+*************************
+
+There are a number of boards that ship with GDB that simulate common
+debug scenarios. For example by sshing to a different user on the
+local machine and running gdbserver as this alternative user we aim to
+simulate a true remote debug experience.
+
+There is a script binutils-gdb/gdb/testssuite/make-check-all.sh which
+can be used to run a defined set of tests using all of the available
+simple board files. Support for using this script is also included in
+GDB's makefile, and can be used as:
+
+ make check-all-boards GDB_TARGET_USERNAME=remote-target \
+ GDB_HOST_USERNAME=remote-host \
+ TESTS="gdb.base/break.exp"
+
+The 'remote-target' and 'remote-host' can be replaced with any user
+names on the local machine, the only requirements are that the current
+user must be able to ssh to these users without a password, and these
+users must be happy to have arbitrary files copied into their $HOME
+directory. Ideally, these users would be setup just for GDB testing.
+
+The check-all-boards target requires that TESTS be defined, though it
+is fine to include multiple tests.
+
+The results are preserved, and can be found in the directory
+gdb/testsuite/check-all/. The results are split by the board file
+used.
