OpenJDK-8: Crypto performance is very slow on ARMv7

[Srinivasa Rao Ragolu]

Hi Andrew,

I got below compilation errors when I comment (PACKAGECONFIG_append_arm = "
zero" )
I am using 15 months ago source code ie: hotspot
--> d7b01fb81aa8(changeset). I hope it has jit compiler support. And I am
building from aarch32-port.

Errors:
