Yes, I've run into this problem too. I had to work around that with the
following patch:

diff -p -r1.62 Makefile.target
*** Makefile.target     13 Mar 2005 16:52:10 -0000      1.62
--- Makefile.target     14 Mar 2005 09:17:00 -0000
*************** endif
*** 120,126 ****

  ifeq ($(ARCH),i386)
  CFLAGS+=-fomit-frame-pointer
! OP_CFLAGS=$(CFLAGS) -mpreferred-stack-boundary=2
  ifeq ($(HAVE_GCC3_OPTIONS),yes)
  OP_CFLAGS+= -falign-functions=0 -fno-gcse
  else
--- 120,126 ----

  ifeq ($(ARCH),i386)
  CFLAGS+=-fomit-frame-pointer
! OP_CFLAGS=$(CFLAGS) -mpreferred-stack-boundary=4
  ifeq ($(HAVE_GCC3_OPTIONS),yes)
  OP_CFLAGS+= -falign-functions=0 -fno-gcse
  else

Sincerely,
