test/CMakeLib: make testUVProcessChain work with qemu
When building and testing CMake in a container with qemu
user mode emulation, the expected termination with std::abort()
in testUVProcessChainHelper
leads qemu to emit an additional
message about an uncaught signal. There appears to be no way
to make qemu shut up, so this exact message will be removed
in the output validation of the test.
I'm open to a different solution, but I'd like to build and verify recent CMake releases in my Docker CI images.
