The following worked for 2.2.16 kernel, so it _may_ work for > 2.3 as
well.

find this line in /usr/src/linux/Makefile,...

  # use '-fno-strict-aliasing', but only if the compiler can take it
  CFLAGS += $(shell if $(CC) -fno-strict-aliasing -S -o /dev/null -xc /dev/null >/dev/null 2>&1; then echo "-fno-strict-aliasing"; fi)

...and add this one

  CFLAGS += $(shell if $(CC) -fno-optimize-sibling-calls -S -o /dev/null -xc /dev/null >/dev/null 2>&1; then echo "-fno-optimize-sibling-calls"; fi)

hth.
