Merge "Add -static to static link command, for clang."

## Commands for linking a static executable. In practice,

## we only use this on arm, so the other platforms don't

## have transform-o-to-static-executable defined.

## Clang driver needs -static to create static executable.

## However, bionic/linker uses -shared to overwrite.

## Linker for x86 targets does not allow coexistance of -static and -shared,

## so we add -static only if -shared is not used.
