The legacy-performance-test-hostdex library was built using the
BUILD_HOST_DALVIK_JAVA_LIBRARY macro (which creates a non-static
library) but is used with LOCAL_STATIC_JAVA_LIBRARIES which
requires a static library. That works with Jack but fails with
the javac toolchain.
This change switched to build legacy-performance-test-hostdex
using the BUILD_HOST_DALVIK_STATIC_JAVA_LIBRARY macro.
Test: make checkbuild
