In dwarf2_32.h, test for CONFIG_AS_CFI instead of CONFIG_UNWIND_INFO. Turns out that searching for UNWIND_INFO returns no match in any Kconfig or Makefile, so we're really just throwing everything away regarding dwarf frames for i386. The test that generates CONFIG_AS_CFI does not have anything x86_64-specific, and right now, checking V=1 builds shows me that the flags is there anyway, although unused.
