And this is exactly the problem I now have - after moving 
sysdeps/x86_64/elf/start.S to sysdeps/x86_64, the start.S file from 
sysdeps/unix is choosen instead of the sysdeps/x86_64 version.

I'm appending my current list of patches - without changelog - for 
reference in case an expert on sysdirs wants to have a look and continue.

With the patches sysd-rules starts with:
sysd-rules-sysdirs := nptl/sysdeps/unix/sysv/linux/x86_64 
sysdeps/unix/sysv/linux/x86_64 sysdeps/unix/sysv/linux/wordsize-64 
nptl/sysdeps/unix/sysv/linux nptl/sysdeps/pthread sysdeps/pthread 
sysdeps/unix/sysv/linux sysdeps/gnu sysdeps/unix/common 
sysdeps/unix/mman sysdeps/unix/inet nptl/sysdeps/unix/sysv 
sysdeps/unix/sysv sysdeps/unix/x86_64 nptl/sysdeps/unix sysdeps/unix 
sysdeps/posix sysdeps/x86_64/fpu/multiarch sysdeps/x86_64/fpu 
sysdeps/x86_64/multiarch nptl/sysdeps/x86_64 sysdeps/x86_64 
sysdeps/wordsize-64 sysdeps/ieee754/ldbl-96 
sysdeps/ieee754/dbl-64/wordsize-64 sysdeps/ieee754/dbl-64 
sysdeps/ieee754/flt-32 sysdeps/ieee754 sysdeps/generic/elf sysdeps/generic
