openjdk-8: add aarch32 port 8u172b11

Similar to the aarch64 build, we import the specific aarch32 port when
building for ARMv7. We also add all the necessary patches to:
* compile using gcc v8
* compile against musl

This was tested on:
* QEMU with cortex A7 emulation (using glibc)
* real hardware (using musl)
