cross compile OpenJDK-9+158 minimal variant failed when link libjvm.so

[Zhu Yong]

Yes, the fix for arm-vfp-sflt must apply, otherwise, build will fail before
linking libjvm.so.

it's is weird that your build can pass linking of libjvm.so with the 8
doit() implementations in jvmtiEnvBase.hpp but related jvmti cpp files
excluded.
