This patch to src/lwp/Makefile.in in combination with the other ucontext 
patch to param.arm_linux26 allowed the build to complete on aarch64 and 
I now have a full set of am64 debs for Ubuntu 14.04. I put the two 
patches together and have attached it here as well as the Ubuntu bug report.

Is it possible to get this included in a 1.6.8 or future release?

Thank you all for your help.
