* Detect kernel rcu_sched stall + cosmetic improvements
* Start QEMU with options '-nographic -monitor none'. Without this,
QEMU cannot be run on the Travis servers which have no display.
'-monitor none' is needed when '-nographic' is set and one wants to
redirect serial port 0 (first occurrence of '-serial stdio'), otherwise
a conflict occurs and the following message is shown:
    qemu-system-arm: -serial stdio: cannot use stdio by multiple character
    devices
* Fix undefined variable error on timeout
* Set LD_LIBRARY_PATH. The libraries that come with the compiler
sometimes end up under /lib, or under /lib/arm-linx-gnueabihf. By setting
LD_LIBRARY_PATH we support both.
* Catch kernel panic/timeout on boot to make the script more robust.

- If $(CROSS_COMPILE) is defined, use it to set the other cross compile
variables used in common.mk: CROSS_COMPILE_{S,NS}_{USER,KERNEL}.
The linux and qemu targets are also adjusted to use those variables,
they may be updated later when common targets are added.
- Use $(MAKE) instead of plain 'make' so that some special make flags
are handled properly (-n for instance).
- Fix filelist-tee dependencies. Since this target uses 'find' to make
a list of files built by xtest, xtest is a dependency.
- make check: add DUMP_LOGS_ON_ERROR variable. To dump serial0.log and
serial1.log when test fails, run:
    make check DUMP_LOGS_ON_ERROR=1
- Add missing + before $(MAKE). The $(bios-qemu-common) macro defines
a command that must start with a '+' character for reasons related to
the GNU make jobserver implementation [1]. Without it, the sub-make
would print the following warning and not run in parallel:
    make[1]: warning: jobserver unavailable: using -j1.  Add `+' to
    parent make rule.

The code added by commits d6536da6 ("Commonlize xtest compilation
among all platforms") and 070d9559 ("common build: optee
components") introduces race conditions that break parallel build (make
-jX). This is due to manually launching a make sub-process to run the
-common targets, and can be fixed by just declaring a dependency
instead. Specific flags are appended to common flags, rather than
passed as arguments to a new "make" sub-process.

So, basically:

 foo-common:
 	$(MAKE) -C foo_dir [A=a B=B]

 foo:
 	$(MAKE) foo-common [C=c]

is turned into:

 FOO_COMMON_FLAGS ?= A=a B=b
 foo-common:
 	$(MAKE) -C foo_dir $(FOO_COMMON_FLAGS)

 FOO_COMMON_FLAGS += C=c
 foo: foo-common

At the same time this allows foo: to override flags, for instance
set A=aa in the above example (prior to this, A=a would have had a
higher priority).

This is the first patch of a serie that show how makefile for specific
platform support may use common rules. comon.mk is introduced. It contains:
- common variable definitions, such as the compilers
- common git to use and path (typically the OP-TEE ones)
- common macros (CCACHE, and others to come).

Adds an Expect script to launch QEMU, run xtest and return a pass/fail
status. This makes it even easier to launch non-regression tests and
possibly integrate into a CI loop.

The script may be invoked through 'make check' or 'make check-only'.
The former considers dependencies, while the latter just runs the script.

The output of serial ports 0 and 1 are saved to serial0.log and
serial1.log, respectively.

Expect may be installed with 'sudo apt-get install expect' on Debian/
Ubuntu distributions.

Sample output:

 $ make -j9 check

 expect qemu-check.exp -- \
         --bios /home/jerome/work/optee_repo/out/bios-qemu/bios.bin

This is the first commit containing helper makefiles to be able to build
OP-TEE easily regardless of previous knowledge of OP-TEE.

To use this particular git and the makefiles, you should have installed
the environment according to the instructions at:
  https://github.com/OP-TEE/manifest/blob/master/README.md



In this commit there are support for building OP-TEE for:
 - QEMU (default)
 - FVP
 - Hikey

More targets will be added later on.
