Please look at the test case for SETCONTEXT_CLOBBERS_TLS in libgo/configure.ac
and figure out why it fails on arm-linux-gnueabi. That test case should not
fail on any GNU/Linux system, so I am surprised that SETCONTEXT_CLOBBERS_TLS is
being defined. It may simply be some oversight in the test case.

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.

If ARM GNU/Linux does not support getcontext/setcontext, then this particular
configure test is not particularly relevant, since the library isn't going to
work anyhow. I suppose the error message could be more clear but it's going to
boil down to a compilation or runtime error regardless.

The getcontext() routines have now landed in glibc-ports and should be
available in glibc 2.16:
http://sourceware.org/ml/libc-ports/2012-02/msg00079.html
I'll ask if they can be included in Ubuntu Precise.
