In order to properly verify that this works, one needs a big-endian (the minimum supported CPU for 64-bit little-endian is power8 anyway) GCC configured with --enable-checking (see GCC commit e154242724b0 ("[RS6000] Don't pass -many to the assembler").

This requires configuring the real-time signal mapping, and therefore some knowledge about the host. To this end, pass the emulator path in the QEMU environment variable to all tests (this should not disturb the existing ones), and assume that all hosts have signals 36-39 available.
