Before, the Android exec wrapper expected the trailing exit code
output on its own line, like this:

PASS
exitcode=0

However, some tests can sometimes squeeze in some output after
the test harness outputs "PASS" and the newline. The
TestWriteHeapDumpFinalizers test is particularly prone to this,
since its finalizers println to standard out. When it happens, the
output looks like this:

PASS
finalizedexitcode=0

Two recent failures caused by this race:

https://build.golang.org/log/185605e1b936142c22350eef22d20e982be53c29
https://build.golang.org/log/e61cf6a050551d10360bd90be3c5f58c3eb07605

Since the "exitcode=" string is always echoed after the test output,
the fix is simple: instead of looking for the last newline in the
output, look for the last exitcode string instead.

go_android_exec is looking for "exitcode=" to decide the result
of running a test.  The heap dump test nondeterministically prints
"finalized" right at the end of the test.  When the timing is just
right, we print "finalizedexitcode=0" and confuse go_android_exec.

This failure happens occasionally on the android builders.

Any defer in a shared object crashed when GOARCH=386. This turns out to be two
bugs:

 1) Calls to morestack were not processed to be PIC safe (must have been
    possible to trigger this another way too)
 2) jmpdefer needs to rewind the return address of the deferred function past
    the instructions that load the GOT pointer into BX, not just past the call

Bug 2) requires re-introducing the a way for .s files to know when they are
being compiled for dynamic linking but I've tried to do that in as minimal
a way as possible.

The test for #9400 relies on an assembler function that manipulates
the stack pointer. Meanwile, it uses a global variable for
synchronization. However, position independent code on 386 use a
function call to fetch the base address for global variables.
That function call in turn overwrites the Go stack.

Fix that by fetching the global variable address once before the
stack register manipulation.
