util/crossgcc/buildgcc: Remove CROSSGCC_COMMIT

For reproducibility, the buildgcc script is copied to the destination
folder of the toolchain. `CROSSGCC_COMMIT` is used as a file name
extension for the script and was introduced when `CROSSGCC_VERSION`
didn't contain the commit yet. Since this is not the case anymore,
remove it.
