Back to work on packaging @hare for @fedora, let's see how much I can bang out in a few hours. The resulting artifacts are going to be fairly simple, but not particularly packager friendly. That's a day-2 project.
New cross-compile meta packages for #GNU and #LLVM dependencies.
I've created a convenience script, harex, to switch to non-GNU toolsets. Just set HARE_XCOMPILE_TOOLCHAIN to "llvm". User specified env vars will still be respected.
