Hi Adrian,

Sorry for late answer. I though you will begin work few hours later.

That is the toolchain issue. BASELIB has to be set to 'lib64', so 
ld-linux-aarch64.so.1 is installed to /lib instead of /lib64. Please try 
patch attached that I redefined the dynamic linker position.

Subject: [PATCH] gcc-4.9: redefine dynamic linker for aarch64

Redefine dynamic linker for aarch64 from /lib to /lib64.

BASELIB of aarch64 has to be defined with 'lib64', then linker file
ld-linux-aarch64.so.1 is installed into /lib64 rather than /lib. So
update it here too.
