The definition and most uses of MAKECONTEXT_STACK_TOP in libgo were
removed in https://golang.org/cl/88660043, which removed support for
Solaris 8/9. One use of MAKECONTEXT_STACK_TOP was accidentally left
in the source code. Remove it now. Bootstrapped and ran Go testsuite
on x86_64-pc-linux-gnu. Committed to mainline.
