If you read what I said:
"I believe for glibc, these are simply unimplemented on ARM, and linking
a program which uses makecontext with glibc would result in the linker
issuing:"
These calls are nothing to do with the kernel. They're a subject purely
for glibc. So there's no modification to the Linux kernel source code
which could effect their implementation.
