Yes, before I promote each build, I do a build on RHEL 7 on
ppc64, ppc64le, x86_64, and x86 and Zero (ppc32, s390x, aarch64).
I have fixes in the pipeline which should enable the aarch64 JIT [0]
and s390 (31-bit) on Zero.

Specifically to this particular change, it also went out in the last
release of IcedTea [1] so it's had testing there as well. It should
actually make cross-compilation easier (it allowed me to exclude
one related change from the AArch64 patch)
