MSPM0G3519-Q1: How to use command line to build the MSPM0 project

Hi Leo,

I think customer could find some guidance in GNU-Syntax Arm Assembly Language Reference Guide — TI Arm Clang Compiler Tools User's Guide.

And also they could import any an example from SDK which end with "_gcc", and then build the project. And the default compiler options could be found in Console window for GNU compiler.
