Andrew, could you put a new entry into the Linux FAQ suggesting that

  CFLAGS+= -m486

or (for the new compilers that most people are not yet running)

  CFLAGS+= -mpentium
or
  CFLAGS+= -mpentiumpro

be added to Makefile.custom? Otherwise people are going to get 386 code generation
for most installations...
