Segfault on PPC GNUSPE

[alucryd]

Steps to Reproduce

1. Build a powerpc-unknown-linux-gnuspe toolchain with crosstool
2. Build mono 6.12.0.182
3. Try running emby with the built mono (https://github.com/MediaBrowser/Emby.Releases/releases/download/4.7.12.0/embyserver-netframework_4.7.12.0.zip)

Current Behavior

We run our server on a variety of old devices using mono, it's working pretty much great everywhere (including armv5te) but fails on ppc gnuspe. We have a workaround for ther arm platforms but it's not working for this particular one. Workaround is passing -O=-aot,-float32,-inline.

Expected Behavior

The server should not segfault. I understand PPC is community-supported, but any help would be appreciated.
