[PATCH 1/3] gdb/testsuite: missing ';' in check-all-boards rule

The check-all-boards makefile rule was missing a semicolon.  As a
result we would pass "result=0" through to the make-check-all.sh
script.

This 'result=0' would end up inside the TESTS="..." string which was
passed to the 'make check-...' command.  As 'result=0' doesn't match
any of GDB's .exp files the 'result=0' would then be ignored.

Back in the Makefile, due to the missing semicolon, as the
'result=...'  line had become an extra argument to make-check-all.sh,
we were no longer capturing the exit status of the make-check-all.sh
script.  This means that when the 'check-all-boards' rule completed we
actually exited with the exit status of the last command rather than
with the exit status of the make-check-all.sh script.

Fix this by adding in the missing semicolon.

There should be no changes in what is tested after this commit.
