Can't anymore test ARM and uARM toolchain

[svastm]

After the merge #1691 it's not anymore possible to use the command singletest.py with both uARM and ARM toolchain. The ARM part fail build when uARM is also used. If ARM is used alone, no problem.

The problem come from arm.py. The ARM_STD and ARM_MICRO class share a reference self.flags to DEFAULT_FLAGS and when ARM_MICRO object is created, it add, amongst others, --library_type=microlib in the DEFAULT_FLAG and then in the self.flags of ARM_STD object.

A fix could be to copy the DEFAULT_FLAGS line 57.

self.flags = copy.deepcopy(self.DEFAULT_FLAGS)

Another problem is that the uARM toolchain is always in timeout. Can you verify this point ?

exemple with nucleo_l031k6 :

Hi @svastm, I'm having trouble reproducing your issue on the K64F. Are you using the latest master? If so and you're still seeing the same issue, could please post the following info?

1. The platform you're testing
2. The commands you're using
3. The errors you're seeing
4. The version of armcc you're using

I have the issue with, at least, NUCLEO_L031K6. and the updated master (HEAD: 9cef243de23875778f461bbe9a8c1bc47e65212b) when I use the following command:

python ..\mbed\workspace_tools\singletest.py --auto -f NUCLEO_L031K6,NUCLEO_L053R8,NUCLEO_L073RZ,DISCO_L053C8 --parallel --tc uARM,ARM,IAR,GCC_ARM --global-loops=1 --clean -j 4 -c copy -V -v --report-html=.\reports\report__2016-05-04_12.59.53.67__L0__common__ALL.html -C

with armcc version 5.6.0.13.

During an ARM_STD compilation, I have the following line where the options --library_type=microlib and -D__MICROLIB should not be present, I guess.

Compile: main.cpp

Then the link fail :

@svastm Thanks for reporting, I'll have a look at those microlib flags

Should be fixed. I was able to run uARM test, and also both ARM and uARM. Please verify, and reopen with more info if this problem persists.

Thanks for the description with the solution for this bug, appreciated 👍
