genlink: avoid creating blank linker script if gcc fails 

When piping to a file, if arm-none-eabi-gcc is not present in the path,
a blank linker script is created with genlink. After sourcing a bash
script to add GCC to the path, the linker script doesn't get rebuilt
due to a fresh timestamp despite failing to generate.
