qbs runs clang++ with the invalid target argument: -target x86_64-unknown-freebsd14.3-STABLE-unknown

Build fails because this command fails:
> ERROR: /usr/local/libexec/ccache/clang++ -g -O0 -Wall -Wextra -Werror -target x86_64-unknown-freebsd14.3-STABLE-unknown ...
> ERROR: clang++: error: version 'STABLE-unknown' in target triple 'x86_64-unknown-freebsd14.3-STABLE-unknown' is invalid
> ERROR: Process failed with exit code 1.

Why is -target even used? It should build for the current target.
