firefox build (again)

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Latest issue with buidling Firefox on i386:

  cargo:warning=src/rasterize.h:782:20: internal compiler error: in convert_move
, at expr.c:231
  cargo:warning= static inline void draw_quad_spans(int nump, Point2D p[4], uint32_t z,
  cargo:warning=                    ^~~~~~~~~~~~~~~
  cargo:warning=no stack trace because unwind library not available  cargo:warning=Please submit a full bug report,
  cargo:warning=with preprocessed source if appropriate.
  cargo:warning=See <http://www.NetBSD.org/support/send-pr.html> for instruction
s.
  exit code: 1

I tried to rebuild rust with all possible --llvm-libunwind options, no
improvement. Any hint?
