This is an indirect consequence of the LLVM update for bug 1376213. In
the initial llvm-3.8.1-1 update, ajax enabled the Mips target, but this
was never pushed out due to unrelated build issues. Then later I found
I needed an LLVM update for s390x, so I fixed those issues too and
pushed out llvm-3.8.1-2.
Rust detects the available targets when rustc is built, and this is its
first update using llvm-3.8.1-2, so now it has picked up the Mips target
and uses Mips-related symbols. But this is a compatibility hazard, and
there's no sort of symbol versioning on these per-target symbols.
I think I can fix the rust dependency with a manual entry:
Requires: llvm-libs%{?_isa} >= 3.8.1-2
But is that the best we can do at this point? Any other options?
