compile from source fails on aarch64

[daniejstriata]

I'm trying to build sad into a RPM package. I am not using the distros rust as some distros rust package is too old. That means I have to download and install rust/cargo. Here is the portion of the code:

# Install Rust using curl
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
export PATH="$PATH:$HOME/.cargo/bin"
$HOME/.cargo/bin/cargo build --release --all-features

The build on x86_64 succeeds but because the config.toml contains cross-compilation for aarch64 the build fails to compile on actual aarch64 with the error below:

  Compiling unicode-ident v1.0.12
   Compiling rustix v0.38.32
   Compiling autocfg v1.1.0
error: linker `aarch64-linux-gnu-gcc` not found
  |
  = note: No such file or directory (os error 2)

I see that there is a line in BUILD/sad-0.4.28/.cargo/config.toml that needs to be deleted if building on aarch64. The same issue is being referenced here for NixOS: https://github.com/NixOS/nixpkgs/issues/145726

I've built a RPM for a couple of distros in COPR here: https://copr.fedorainfracloud.org/coprs/faramirza/sad/ I'll check if they work and will revert back here.

So far the COPR builds I've tested works fine. Will need to install some VM's for Magia and OpenMandriva to test them on.

sad works as expected on Magia and OpenMandriva.
