disable libwebrtc on i686 to fix illegal instructions

Both Parabola and archlinux32 whish to support all i686 machines
that don't have SSE2:
- Parabola's minimum system requirements states that:
  "Parabola GNU/Linux-libre should run on any i686 compatible machine
  [...]"[1]
  Wikipedia states that i686 has MMX and SSE[2] but doesn't mention
  SSE2 as a requirement[2].
- Archlinux32 states:
  "Currently some i686 packages require SSE2 - which is a bug we're
  trying to solve."[3]
