[gen3] fixes .particle/toolchains/gcc-arm/5.3.1/bin/objdump: not found issues in WB

[avtolstoy]

Problem

For some reason building things out of main with WB is broken now (at least with deviceOS@source) and fails with not being able to find objdump:

/bin/sh: 1: /home/avtolstoy/.particle/toolchains/gcc-arm/5.3.1/bin/objdump: not found
/bin/sh: 1: /home/avtolstoy/.particle/toolchains/gcc-arm/5.3.1/bin/objdump: not found

And consequently failing to link:

/home/avtolstoy/.particle/toolchains/gcc-arm/5.3.1/bin/../lib/gcc/arm-none-eabi/5.3.1/../../../../arm-none-eabi/bin/ld: Insufficient room for .data and .bss sections
/home/avtolstoy/.particle/toolchains/gcc-arm/5.3.1/bin/../lib/gcc/arm-none-eabi/5.3.1/../../../../arm-none-eabi/bin/ld: region `SRAM’ overflowed by 1196 bytes
collect2: error: ld returned 1 exit status

Solution

The makefile that generates some linker RAM definiitions in runtime for Gen 3 user modules is including invalid support makefile, which doesn't correcty define all the tools that use GCC_PREFIX.

Steps to Test

Build a simple app with deviceOS@source

looks good. i tested within workbench - here are the steps:

1. configure workbench to use the deviceOS@source toolchain (docs)
2. run the Particle: Create Project command and follow the prompts
3. when your new project loads, copy simple firmware into your ./src/<project-name>.ino file:

void setup() {
    pinMode(D7, OUTPUT);
}

void loop() {
    digitalWrite(D7, HIGH);
    delay(1000);
    digitalWrite(D7, LOW);
    delay(1000);
}

4. from VSCode's main menu, select "Terminal" > "Run Task..."
5. from the list presented, select the Particle: Compile application (local) task

when running against the develop branch, i see the objdump: not found error. when running against this branch (fix/gen3-build-objdump-not-found), i no longer see the error 👍
