Avoid exception by improving `makefile.additionalCompilerNames` handling to automatically escape characters like `+`

Hi,

I'm trying to setup makefile tools to be able to cross compile for Nios II within vscode and have run into the same issue when attempting to run Makefile: Configure, Makefile: Clean Configure. On attempting to Debug or Run I see: Cannot run because there is no launch configuration set and the list of launch targets is empty. Double check the makefile configuration and the build target. (The build target is set to all and the build is successful) I have defined a launch target in a launch.json file but there doesn't seem to be a way of selecting this or associating it with my Makefile project.

When I attempt to run Makefile: Configure I see the following output:

The project needs a configure to populate the launch targets correctly.
