Hi,
The following diff makes i386 to be compiled without --enable-rust-simd.
simd is "Single instruction, multiple data" (aka MMX, SSE, SSE2...).
rustc when compiled with external LLVM doesn't export target_features as
compilation variable, making firefox building to fail.
I workarounded the problem on amd64 by manually exported SSE2 symbol
(always present on amd64). But for i386, same hack isn't possible (as
not all i386 processors have such extensions). So it is preferable to
not enable simd on i386.
I tested the diff with rustc 1.22.1 and firefox still build well (but no
runtime test).
Thanks.
