The testcshared test.bash was rewritten in Go, but the rewritten script
broke on Android. Make the tests run on Android again by:
- Restoring the LD_LIBRARY_PATH path (.).
- Restoring the Android specific C flags (-pie -fuse-ld=gold).
- Adding runExe to run test executables. All other commands must run on

The hardware divider is an optional component of ARMv7. This patch
detects whether it is available in runtime and use it or not.
1. The hardware divider is detected at startup and a flag is set/clear
according to a perticular bit of runtime.hwcap.
2. Each call of runtime.udiv will check this flag and decide if
use the hardware division instruction.
A rough test shows the performance improves 40-50% for ARMv7. And
the compatibility of ARMv5/v6 is not broken.

The gold linker is used by default in the Android NDK, except on
arm64:
https://github.com/android-ndk/ndk/issues/148
The Go linker already forces the use of the gold linker on arm and
arm64 (CL 22141) for other reasons. However, the test.bash script in
testcshared doesn't, resulting in linker errors on android/arm64:
warning: liblog.so, needed by ./libgo.so, not found (try using -rpath or
-rpath-link)
Add -fuse-ld=gold when running testcshared on Android. Fixes the

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.
