Compaction isn't available on this platform

Hello,

while doing update to msgpack 1.4.4 for Fedora, I've encountered issue on ppc64le (exclusively). Part of Fedora package build, we run the test suite.
I'm hitting similar issue to https://bugs.ruby-lang.org/issues/18133:

+ rspec -Ilib -I/builddir/build/BUILDROOT/rubygem-msgpack-1.4.4-1.fc37.ppc64le/usr/lib64/gems/ruby/msgpack-1.4.4 spec
