Updated sed expression to escape hash character for compatibility across versions of GNU make.

I personally ran into this on macOS 27.0.1 with Apple's version of GNU make 3.81:
$ make --version

I presume this was shipping with Xcode. Weird that this is still the x86 variant. Anyway.
The version shipping with brew did not have that problem.
$ /opt/homebrew/bin/gmake --version

On a meta-level, I am trying to find a way to contribute from where my current routine is residing, and this is on a mac. I do not expect the mac to start controlling any serious hardware in real-time, but I do expect it to be capable to communicate with LinuxCNC controllers. So, I now just want to see how far the current code base carries me. And if there are any low-hanging fruits the improve the compatibility of LinuxCNC then I hope to address these before the release branches.

It is not necessarily the LANGUAGES assignment per se but the combination with then following echo in the line below.
It is not observed for all versions of Make as it seems. The stable branch does not have this sed expression.
