Add EBcLfSA Toolchain (#28)
* Add EBcLfSA Toolchain Added "aarch64-linux-sdk_0.1.0-ebclfsa", a GCC-based toolchain for EB corbos Linux for Safety Applications. This is *not* the final toolchain, since that will require a clang-based compiler and a special libc. However, it can be used to demonstrate functionality. # Conflicts: # examples/MODULE.bazel # extensions/gcc.bzl * Switch to official pre-release 2.0.0-beta1 of EB corbos Toolkit
