NetBSD doesn't put packages in /usr/local like /CMakeLists.txt thought.
The `#ifdef __NetBSD__` around iconv was actually breaking compilation
on NetBSD when using the system libiconv (there's also a GNU iconv
package)
A C program included from C++ source broke on NetBSD specifically, work
around it.
This doesn't fix compilation on NetBSD, which is currently broken, but
is closer to correct.
967280f140 broke linking against
libLLVM.so because it used the outdated way to link against LLVM from
CMake. This causes a compilation failure on systems that don't have the
LLVM static libraries, such as Arch Linux. On systems that have the
static libraries, it'll use them and increase binary sizes massively.
Switch to the newer llvm_config CMake macro from LLVM.
