Avoid building staticlib

[holdxen]

My OS is macOS arm64. My rust project depends on some prebuild arm64 C shared libraries, so it can't be compiled into staticlib or x86_64 library. But frb and cargokit always try to compile rust into staticlib and x86_64 library. In my opinion, my project is a desktop application, so FRB should only need the dynamic library, not the static one — and certainly not the x86 version (at least during the debug phase). How to solve this problem?

hmm looks like this is related to compilation, thus maybe check cargokit doc (or issue) about solutions. my naive guess is maybe there is a flag to disable it
