Summary

This PR fixed aarch64 cross-build support.

And this PR will remove not well maintained target support including:

• armv7-unknown-linux-gnueabihf
• arm-unknown-linux-gnueabi

No one really uses them and they are not covered by CI.

Let's add them back until we are ready to maintain them.

NOTICE: After this PR get merged, we need to push the built image to dockerhub.

Detailed explain

The original rustembedded/cross:aarch64-unknown-linux-gnu image doesn't have lib we need, so cross build --target aarch64-unknown-linux-gnu will meet errros like:

  running: "aarch64-linux-gnu-gcc" "-O0" "-ffunction-sections" "-fdata-sections" "-fPIC" "-g" "-fno-omit-frame-pointer" "-I" "/usr/include" "-Wall" "-Wextra" "-E" "build/expando.c"
  cargo:warning=build/expando.c:2:33: fatal error: openssl/opensslconf.h: No such file or directory
  cargo:warning=compilation terminated.
  exit status: 1

  --- stderr
  thread 'main' panicked at '
  Header expansion error:
  Error { kind: ToolExecError, message: "Command \"aarch64-linux-gnu-gcc\" \"-O0\" \"-ffunction-sections\" \"-fdata-sections\" \"-fPIC\" \"-g\" \"-fno-omit-frame-pointer\" \"-I\" \"/usr/include\" \"-Wall\" \"-Wextra\" \"-E\" \"build/expando.c\" with args \"aarch64-linux-gnu-gcc\" did not execute successfully (status code exit status: 1)." }

  Failed to find OpenSSL development headers.

  You can try fixing this setting the `OPENSSL_DIR` environment variable
  pointing to your OpenSSL installation or installing OpenSSL headers package
  specific to your distribution:

      # On Ubuntu
      sudo apt-get install libssl-dev
      # On Arch Linux
      sudo pacman -S openssl
      # On Fedora
      sudo dnf install openssl-devel

  See rust-openssl README for more information:

      https://github.com/sfackler/rust-openssl#linux
  ', /cargo/registry/src/github.com-1ecc6299db9ec823/openssl-sys-0.9.71/build/main.rs:162:13
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
warning: build failed, waiting for other jobs to finish...
error: build failed

In the past, we fixed this problem via self-compiled openssol with hardcoded OPENSSL_DIR and other envs.

RUN apt-get update && \
    apt-get install -y wget
COPY docker/build-tool/openssl.sh /
RUN bash /openssl.sh linux-armv4 arm-linux-gnueabihf-
ENV OPENSSL_DIR=/openssl \
    OPENSSL_INCLUDE_DIR=/openssl/include \
    OPENSSL_LIB_DIR=/openssl/lib

However, it's not enough. We will meet other problems like the following:

  = note: /usr/bin/ld: cannot find -lz

error: build failed

The real problem here is we pkg-config doesn't have current path.

So we only need to set the PKG_CONFIG_PATH correctly like the following:

ENV PKG_CONFIG_PATH=/usr/lib/aarch64-linux-gnu/pkgconfig:$PKG_CONFIG_PATH

And we can add new packages like:

RUN dpkg --add-architecture arm64 && \
    apt-get update && \
    apt-get install --assume-yes libssl-dev zlib1g-dev

The simple, perfect solution.
