clang-cl expects x64, not x86_64

Having run:

xwin splat --output vendor

I want to compile a program with clang-cl on Linux, but lld-link can't find the required libraries on the expected library path:

clang-cl -vctoolsdir vendor/crt/ -winsdkdir vendor/sdk -fuse-ld=lld -v test.c
...
"/usr/bin/lld-link" -out:test.exe -libpath:vendor/crt/lib/x64 -libpath:vendor/crt/atlmfc/lib/x64 -libpath:vendor/sdk/Lib/10.0.20348/ucrt/x64 -libpath:vendor/sdk/Lib/10.0.20348/um/x64 -nologo /tmp/test-eb99a8.obj
lld-link: error: could not open 'libcmt.lib': No such file or directory
lld-link: error: could not open 'oldnames.lib': No such file or directory
lld-link: error: could not open 'uuid.lib': No such file or directory
clang-15: error: linker command failed with exit code 1 (use -v to see invocation)

If I manually symlink the nested x86_64 subdirectories to x64, the above clang-cl command completes successfully.

You need to use --preserve-ms-arch-notation to use the /vctoolsdir and /winsdkdir options

Thanks; I didn't realise the subcommands had help, i.e. xwin splat --help.
