It is relevant because in this case "another work" (Microchip's C
library with associated header files) is not, as far as I am aware,
based in any way on "the Program" (gcc). If they haven't used any
GPLed code to create their library then the GPL doesn't apply to it.
Bundling gcc and their C library into one package is simply aggregation.

The GPL applies to GPLed source code and binaries created by
compiling/assembling that source code. It doesn't apply to other
programs that are bundled together with them in a single package.

That means simply a program/library that is licensed under the GPL.
It doesn't mean a tarball, zipfile, Windows installer, etc. that
contains both GPLed programs and non-GPLed programs.

Rowley sell an ARM development environment that bundles ARM GCC with
their own proprietary C library, linker scripts, and IDE.
