Currently Go produces shared libraries that cannot be shared between processes
because they have relocations against the text segment (not text section). This
fixes this by moving some data to sections with magic names recognized by the
static linker.
The change in genasmsym to add STYPELINK to the switch should fix things on
darwin/arm64.

On android the generated header files are located in
pkg/$(go env GOOS)_$(go env GOARCH)_testcshared.
The test was broken since https://go-review.googlesource.com/9798.
The installation path differs based on codegenArgs
(around src/cmd/go/build.go line 389), and the codegenArgs
is platform dependent.

When
using -buildmode=c-archive or c-shared, and
when installing packages that use cgo, and
when those packages export some functions via //export comments,
then
for each such package, install a pkg.h header file that declares the
functions.
This permits C code to #include the header when calling the Go
functions.
This is a little awkward to use when there are multiple packages that
export functions, as you have to "go install" your c-archive/c-shared
object and then pull it out of the package directory. When compiling
your C code you have to -I pkg/$GOOS_$GOARCH. I haven't thought of
any more convenient approach. It's simpler when only the main package
has exported functions.
When using c-shared you currently have to use a _shared suffix in the
-I option; it would be nice to fix that somehow.

Instead of comparing against the entire output that may include
verbose warning messages, use the last line of the output and check
it includes the expected success message (PASS).
