Peter Maydell commented:
Specifically the functions exist but return ENOSYS, which is why this:
if (getcontext (&c) < 0)
abort ();
will abort.
Trying to get these functions into eglibc for ARM is kind of on the Linaro
toolchain group's todo list, but (a) not at a hugely high priority and (b) it
will take a little while for them to percolate through eglibc and back into
distros anyway, so apps/configure scripts need to be prepared to handle the
returns-ENOSYS case anyway.
