Switch to mspgcc 4.7.0
Updated mspsim.jar

The Contiki source code holds a binary version of mspsim.jar until
we get a proper git submodule set up. This particular version of mspsim.jar
is built from Thingsquare's mspsim fork.
Added mspgcc 4.7.x flags
Filter out symbols defined by the C implementation
Parse rodata too
Allow the exit code from a failed test script to propagate to the Java
process, which makes it possible to track failing tests in makefiles and
via scripts.
Turn off the LCD by default as it is somewhat flaky
Merge pull request #306 from adamdunkels/push/travis-mspgcc-4-7-0

Prevent erroneous index creation for non-numerical attributes.
Merge pull request #321 from nvt/antelope-domain-check

Prevent erroneous index creation for non-numerical attributes in Antelope.
Break travis compile tests into smaller builds

* The previous 01-compile test has been renamed to compile-base. It
  now only tests {msp430, avr, native}-based platforms
* New test builds for arm-based and 8051-based ports (one build per arch)
* Only install arm-none-eabi, sdcc and srecord for the builds which need
  them. This will somewhat speed up all other tests
* Test er-rest-example and webserver-ipv6 for the cc2538
* An erroneous comment was fixed and another comment was somewhat
  clarified
Don't try to tail *.testlog after non-sim tests
