Memcached Proxy build in ARM64

Describe the bug
ARM64 build instructions fail because of AMD Lua sources

To Reproduce
I don't have a clear snippet to provide, also because I'm not familiar with C compiling and Lua. If I find one I will add it here.
It should be as easy as running make in ARM64.

Reproduce the ARM64 build from the issue with ./configure --prefix=/usr --enable-proxy, then run make and inspect the failure involving vendor/lua/src. Compare the build output on ARM64 with the stated command sequence; done means the proxy build and make install complete successfully.
