Q: quick building for different targets

[Felixoid]

Hello, and many thanks for the project!

I have a question: is it possible to speed up building for different platforms?

Currently, we do the next thing in a project:

git clone --depth 1 https://github.com/tpoechtrager/cctools-port.git \
    && cd cctools-port/cctools \
    && ./configure --prefix=/cctools --with-libtapi=/cctools \
        --target=x86_64-apple-darwin \
    && make install \
    && make clean \
    && ./configure --prefix=/cctools --with-libtapi=/cctools \
        --target=aarch64-apple-darwin \
    && make install

As it's rebuilding the whole project twice, I think it's suboptimal.

Although, if I don't clean the project via make clean, I have the same files for different platforms:

sha256sum /cctools/bin/* | sort # without clean

So, do you think it's possible to build the project for multiple targets simultaneously?

Is it so rare case, that nobody uses it?
