target: mbedos5: mbed CLI refuses to build if no .mbed file present

[janjongboom]

With the newest release of mbed CLI (1.0.0) it error's when no .mbed file is present in the project root. This breaks builds for JerryScript on mbed OS 5. With this patch we create this file and builds succeed again. We cannot use mbed new because it also creates a new git repository in targets/mbedos5 folder which is not what we want.

It seems to be working, but the error message still appears...

Thanks for the feedback, the output you describe is as expected and is a known limitation of the mbed build system. ARMmbed/mbed-cli#283
