Detect toolchain gcc version to --version from -v

Brief Issue Summary

This is a very nice extension, but I am unable to run other GCC toolchains because I cannot detect the GCC version.

Can add detect toolchain gcc version to --version from -v ?
for example:
aarch64-linux-gcc -v is not work , change the full args --version can work,

Additional Information

No response

Start by tracing the toolchain version probe shown in the diagnostic log, focusing on where CMake Tools invokes the GCC executable with -v. Compare that probe with the requested --version behavior for aarch64-linux-gcc, and verify that cross-compiler detection succeeds without breaking existing compiler checks.
