Added "aarch64-linux-gcc-ebclfsa-0.1.0", 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. Hence, this has a pre-1.0.0 version.

This is based on #23, so that one should very likely go in first, and then this one should be re-based and merged.

There is one open question here: EBcLfSA requires an additional tool to be available. It is called "ELF-Enabler". The purposed of the tool is to post-process an ELF-binary and mark it as "High-Integrity Application (HI-Application; "safe executable", colloquially speaking). This tool will, of course, not exist in any other toolchain. How can such a tool be integrated cleanly? The previous method can be seen in this diff (search for elf_enabler).

On top of this one I have this proposal elektrobit-contrib@955ca88

It adds LD_LIBRARY_PATH support for toolchains, so that the tools themselves actually pick up the path from the sysroot, not the host. However, it is not finished yet I tink, since now this filegroup is mandatory...

I have finally fixed the issue that the toolchain could not work with Bazel sandbox. As it turns out, now also this LD_LIBRARY_PATH hack is not required anymore. - wrong, it is required

Add EBcLfSA Toolchain
5c5f656 
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.

LD_LIBRARY_PATH in every package file can be avoided, but we will create follow up on this.
