Having multi-build together

I want to build a lib that work in multi-Android arch, so I added all the targets:

$ rustup target add x86_64-linux-android aarch64-linux-android armv7-linux-androideabi i686-linux-android arm-linux-androideabi

And to avoid having long line at build, like this

$ cargo build --target x86_64-linux-android 

I added the target to the .cargo/conf as:

[build]
target = "x86_64-linux-android"
#target = "aarch64-linux-android"
#target = "armv7-linux-androideabi"
#target = "i686-linux-android"

[target.x86_64-linux-android]
ar = "/Users/hasan/Library/Android/sdk/ndk/20.0.5594570//toolchains/llvm/prebuilt/darwin-x86_64/bin/x86_64-linux-android-ar"
linker = "/Users/hasan/Library/Android/sdk/ndk/20.0.5594570//toolchains/llvm/prebuilt/darwin-x86_64/bin/x86_64-linux-android23-clang"

[target.aarch64-linux-android]
ar = "/Users/hasan/Library/Android/sdk/ndk/20.0.5594570//toolchains/llvm/prebuilt/darwin-x86_64/bin/aarch64-linux-android-ar"
linker = "/Users/hasan/Library/Android/sdk/ndk/20.0.5594570//toolchains/llvm/prebuilt/darwin-x86_64/bin/aarch64-linux-android23-clang"

[target.armv7-linux-androideabi]
ar = "/Users/hasan/Library/Android/sdk/ndk/20.0.5594570//toolchains/llvm/prebuilt/darwin-x86_64/bin/arm-linux-androideabi-ar"
linker = "/Users/hasan/Library/Android/sdk/ndk/20.0.5594570//toolchains/llvm/prebuilt/darwin-x86_64/bin/armv7a-linux-androideabi23-clang"

[target.i686-linux-android]
ar = "/Users/hasan/Library/Android/sdk/ndk/20.0.5594570//toolchains/llvm/prebuilt/darwin-x86_64/bin/i686-linux-android-ar"
linker = "/Users/hasan/Library/Android/sdk/ndk/20.0.5594570//toolchains/llvm/prebuilt/darwin-x86_64/bin/i686-linux-android23-clang"

So, I can compile using cargo build --release

But every time I need to compile for a given target I need to go to the file above, andselect the target I want to compile it, or back for using the --target flag.

Is there a way to combine all the targets in the .cargo/config file, or any other way, so that all the targets are compiled only by running singe command, that is:

$ cargo build --release

I don't think cargo can build multiple targets at once, but you could easily write a wrapper script or makefile that calls each cargo build --target ....
