mbed cli v1.10.0 - GCC_ARM, ARMC6 config needs to have /bin in path, other compilers may not

Version info:

• OS - Linux / Ubuntu 16.04.
• mbed --version 1.10.0

Repro steps:

Download and get gcc arm : https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads

Unarchive it for example under your user folder, i.e. /home/user, for example

jankii01@ubuntu:~/gcc-arm-none-eabi-8-2019-q3-update$ pwd
/home/jankii01/gcc-arm-none-eabi-8-2019-q3-update

Go to one of your mbed examples and configure mbed cli’s path to GCC ARM:

jankii01@ubuntu:~/mbed/mbed-client-testapp$ mbed config -G GCC_ARM_PATH "/home/jankii01/gcc-arm-none-eabi-8-2019-q3-update"

Try compiling, it will fail.

jankii01@ubuntu:~/mbed/mbed-cloud-client-example$ mbed config -G GCC_ARM_PATH "/home/jankii01/gcc-arm-none-eabi-8-2019-q3-update"
[mbed] /home/jankii01/gcc-arm-none-eabi-8-2019-q3-update now set as global GCC_ARM_PATH
jankii01@ubuntu:~/mbed/mbed-cloud-client-example$ mbed compile -m K64F -t GCC_ARM

Add the /bin to the path, and it suddenly works.

However, IAR and ARM C work differently - there you may not add /bin to the path, or they fail.

Requirement: all compiler paths should work in the same way.

I would not prefer to have them in the path, if you need to use multiple versions of the compilers - it’s easier just to use mbed config rather than modify the path.

As this is covered by the documentation I’m closing…
