Right, strictly speaking, GCC prints the program name, then the greeting 
message, then the version.

The binaries in my distribution look like this:

$ arm-none-eabi-gcc --version
arm-none-eabi-gcc (xPack GNU Arm Embedded GCC x86_64) 10.3.1 20210824 (release)

$ arm-none-eabi-gdb --version
GNU gdb (xPack GNU Arm Embedded GCC x86_64) 10.2.90.20210621-git

$ riscv-none-embed-gcc --version
riscv-none-embed-gcc (xPack GNU RISC-V Embedded GCC x86_64) 10.2.0

$ clang-12 --version
xPack x86_64 clang version 12.0.1

$ openocd --version
xPack OpenOCD x86_64 Open On-Chip Debugger 0.11.0+dev (2021-10-17-00:18)


and similarly some other build tools:

$ gcc-xbb --version
gcc-xbb (xPack Build Box x86_64 GCC) 11.2.0

etc

which is fairly different from the more consistent:

$ qemu-system-arm --version
xPack QEMU emulator version 6.2.0 (v6.2.0-1-xpack-arm)


If you prefer the GNU scheme, we can also start with the program name, and it 
would look like:

$ qemu-system-arm --version
qemu-system-arm (xPack QEMU emulator) version 6.2.0 (v6.2.0-1-xpack-arm)

Or something like this, but applied consistently to all binaries.
