[bug#51243] [PATCH] gnu: julia: Fix llvm-julia version

[Jean-Baptiste Volatier via Guix-patches via <guix-patches@gnu.org>]

LLVM bundled in the binary julia distributed by upstream has its
version with a "jl" suffix. The llvm-julia package does not have
this suffix, which causes some packages (e. g. LLVM.jl) to fail to
load.

LLVM.jl does this in order to be sure that it is loading a LLVM as
patched for julia and not LLVM from the distribution which will
lack the correct patches on distribs other than GUIX.

I guess there might be other packages that rely on this, so we
should fix our llvm-julia package.

* gnu/packages/julia.scm (llvm)
[source]: Add missing upstream patch
[arguments]: Add configure-flag to set a "jl" suffix to llvm version
(julia)[arguments]: Symlink llvm to llvm-11jl.so
