Apparently `invoke_as:` directive in GCC spec file applies to running
assembler on C/C++ compiler output. However compiling `assemble` (.s) and
`assembler-with-cpp` pseudo-languages use `as` instead of ${target}-as)
anyway. Fortunately GCC searches for `as` in libexec/gcc/$target/$version
directory. Therefore add symlink to ${target}-as into that directory.
Do the same thing for ar, ld, nm, objcopy, etc just in a case.
This repo contains a spec file for building aarch64 targeted GCC cross-toolchain. The actual sources are in gcc-source, binutils-source, glibc-source, and kernel-source-5.4 packages.
