The problem stemmed from make not recognizing that this file was outdated:
Oct 16 2014 arch/mips/include/generated/asm/ucontext.h
Shouldn't make automatically regenerate outdated files?

The reduced test case can be simplified to these steps:
git co f1fe2d21f4e1aca8644cea888dc618f0183ad671\^1
configure your kernel
ARCH=mips make arch/mips/kernel/signal.o
git co f1fe2d21f4e1aca8644cea888dc618f0183ad671
ARCH=mips make arch/mips/kernel/signal.o
The problem seems to be that if there was a previous build which
resulted in creating an asm-generic wrapper for a file
(arch/mips/include/generated/asm/ucontext.h in that case), but this file
was later moved into an arch-specific, non asm-generic header file, then
we are just not going to automatically remove this auto-generated
wrapper, and generate the new one.
This seems to be aggravated by the fact that commit
f1fe2d21f4e1aca8644cea888dc618f0183ad671 does not add ucontext.h to
arch/mips/include/uapi/Kbuild, Paul, James is that intentional?
After trying to mess a bit with a clean solution, I just gave up and
decided that this was not worth fixing since it is a very infrequent
problem.

We lately had about five people reporting similar issues that all could
be resolved with make distclean.

I suspect it was intended to be exported in kernel headers, for
libc/signal handlers to use, although it isn't referenced by other
headers. Paul?

Thing is it isn't that uncommon. I've lost count of the number of times
I've hit this specific case (especially during bisection), and as Ralf
says, several others have mentioned it on the list, but rm -fr
arch/mips/include/generated always seemed so much easier than fixing
the actual problem.
Anyway, after a bit of fiddling around I think i've fixed this properly
now. I'll submit the patch asap.
Cheers
James

When a header file is removed from generic-y (often accompanied by the
addition of an arch specific header), the generated wrapper file will
persist, and in some cases may still take precedence over the new arch
header.
For example commit f1fe2d21f4e1 ("MIPS: Add definitions for extended
context") removed ucontext.h from generic-y in arch/mips/include/asm/,
and added an arch/mips/include/uapi/asm/ucontext.h. The continued use of
the wrapper when reusing a dirty build tree resulted in build failures
in arch/mips/kernel/signal.c:
arch/mips/kernel/signal.c: In function ‘sc_to_extcontext’:
arch/mips/kernel/signal.c:142:12: error: ‘struct ucontext’ has no member named ‘uc_extcontext’
return &uc->uc_extcontext;
^
Fix by detecting wrapper headers in generated header directories that do
not correspond to a filename in generic-y, and removing them.
