It turns out there's a bug in creating a sub dependency out of threads
in that we pass all of the kwargs from the parent to the
ThreadDependency instance. This demonstrates the bug.
I left a hack patch in a pull request for LLVM, and the result is that
LLVM doesn't link with static builds. The real problem was that some
distros have pkg-config for tinfo, other's don't, so the correct
solution is to use cpp_compiler.find_library if dependency() fails.
Archlinux doesn't package tinfo, and the non-distro maintained package
(in the AUR), doesn't provide a pkgconfig, it just symlinks libncurses.
So just pick something else. glib-2.0 is used elsewhere in meson's test
suite, so that should be safe.
This adds a depdendncy wrapper for llvm-config based on the wxwidgets
dependency. IT handles libs, version, include dir, and the llvm unique
concept of components. These components are individual pieces of the
LLVM library that may or may not be available depending on the platform.
