Subject: libgo patch committed: mark go-context.S as no-exec-stack, split-stack

This libgo patch marks go-context.S as no-executable-stack and
split-stack supported.

The .note.GNU-stack section tells the linker that this object does not
require an executable stack.

The .note.GNU-split-stack section tells the linker that functions in
this object can be called directly by split-stack functions, without
require a large stack.

The .note.GNU-no-split-stack section tells the linker that functions
in this object do not have a split-stack prologue.

Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.

Ian
