Work in progress cross compiler for x86_64. I've managed to get a full x86_64 gcc using the binaries built from foundation, and am working on implementing their builds into tidepool.
### Bootstrapping steps
0) Start with i686 tools (gcc, binutils, musl, etc)
1) Build binutils targeting x86_64-linux
2) Build a minimal gcc cross compiler using the cross binutils. This minimal cross compiler does not have support for libc, so is pretty much only useful for building musl or glibc.
3) Use the minimal cross compiler to build x86_64-linux glibc or musl
4) Now that we have a cross compiler and x86_64-linux libc, we can build gcc for the target architecture!
5) Profit! We can now build anything x86_64 using our gcc compiler!

Make 'missing' executable where source tarballs use autotools and are unpacked with untar. untar doesn't preserve or set mtime, which may result in autotools generated files, e.g. configure, having newer timestamps than their source files (e.g. configure.in.) In these circumstances autotools generated Makefiles will call 'missing' to either regenerate them or fix-up the timestamps.

I must confess to not understanding quite how all this works, but this seems to solve the problem of aarch64 fetching the x86-64 binary and vice-versa.
