Using Arch Linux and clang-arm-gcc-toolchain.cmake, the GCC version can't be parsed due to a trailing space on the regex.
Here is the version string generated:
arm-none-eabi-gcc (Arch Repository) 13.2.0

Running cmake generates the following error, since no version can be extracted:
CMake Error at vendor/arm-cmake/clang-arm-gcc-toolchain.cmake:20 (string):
string sub-command STRIP requires two arguments.
Playing around, I was able to match the version and fix the issue with the following diff:

Did not test it on other distributions but I wonder why the trailing spaces can't be removed altogether, it means the STRIP instruction after it would not be needed as well.
