Travis: Tear out python3 testing to get CI working again

[geky]

Temporary solution, python3 will be added back when working (see #6200)

Travis doesn't recognize version matrices when inside a matrix include job. Instead, it breaks in a way that isn't reported as an error.

Much better than doing nothing silently.

@cmonr, sorry it's not ready yet. Now, travis fails successfully, but we need to fix the tools so it does not.

[cmonr]

@geky Oh, my mistake. Was under the impression that the quick fix was ready. In that case, LMK when it is.

PR not ready yet.

@theotherjimmy - offending line was a suggestion from your side to get the path of build directory, which is used few steps below.
secure_file = join(build_dir, "cmse_lib.o")

Will appreciate to have proper fix from your side, to append the build directory path for cmse_lib.o creation.

[geky]

I added some fixes/workarounds, @theotherjimmy, @deepikabhavnani, if you could review and let me know if you're happy with these for now.

The first error is a unicode problem XD notice the u'...'

Haha, it's not even a real unicode error. It's just that now the config will show that "u" when it has errors, and the tests are checking the error strings.

@deepikabhavnani, I moved the kwargs['build_dir'] into the condition for "secure". This lets the test pass for now, let me know if you're happy with this as a workaround so we can get tool testing back into mbed OS.

[theotherjimmy]

@geky That workaround works, but I would prefer that the offending test just pass in a dummy build_dir parameter. @deepikabhavnani My bad, I thought that line was in the ARM_STD constructor. It makes sense where it is.

@theotherjimmy - Can you please confirm build_dir will not be none for Cortex-M23/M33 devices.

Toolchain init is different for ARM / ARMC6, will this have any impact?

Ok, i was late :-)

[theotherjimmy]

@deepikabhavnani Build dir being None is an error. We need a place to put object files.

[theotherjimmy]

@geky Feel free to delete the test_instantiation test. It adds no value anymore.

[theotherjimmy]

It added value at one point, but no longer.

Cool beans, it's gone now.

@cmonr Should be good to go now. Though no rush, Travis is severly backlogged because of mbed 2 builds.

@cmonr, sorry for the slip up. Should be good to go now (heavy handed solution).

I moved the build dir back into the condition. It looks like none of the other tests pass in build_dir either, but the root of this problem can be fixed in another pr.

Reverting a change that only went in for 5.8 so should have also targeted that release! In fact as this was merged prior to 5.8 rc1 it should already be in that release
