llvm-config outputs the flags that were used to compile LLVM, not the
flags you need in order to compile against LLVM. So, for example, it
outputs -O2 -g on my system amidst its --cflags, which makes it
impossible to make a debug build. I'm not the first one to complain
about this:

    http://llvm.org/bugs/show_bug.cgi?id=4276
    http://llvm.org/bugs/show_bug.cgi?id=9405
    http://llvm.org/bugs/show_bug.cgi?id=8220

That's what.

Since we now care about LLVM, I'd like to fix its build system. Making
llvm.pc seems easier than trying to fix llvm-config.
