hello guix,

i'm totally new to guix and free software development, so bear me if i'm 
doing something wrong.

the 0.10 version of zig just got released[1], with the new self-hosted 
compiler.  during the period of development, i've also submitted a pull 
request[2] for zig, so that we don't need an extra patch file[3] to 
build it on guix.

however, the new zig compiler depends on llvm-15 to build, which is 
unfortunately, not available in guix at the moment.  i personally would 
like to do the work, but lacking the knowledge of both guix and llvm 
makes it almost like an impossible task for me.  so it would be really 
helpful if anyone could help with the packaging of llvm-15.

initially asked on #guix irc channel, csepp suggested me asking on 
guix-devel, hoping to get more attention and help.
