Comment (by kencu):

 disabling the patch is a bit problematic, it turns out, because the
 patches are overlapping and you can't get the asm patch without the no-pie
 patch unless I redo the patches somehow to make them not overlap.

 This might be a better idea anyway. supply the flag if it is needed, and
 not if not needed:
 {{{
 +STAGE1_NO_PIE_FLAG := `case ${host} in *-*-darwin[1-9][1-9]*) echo
 -Wl,-no_pie ;; esac;`
 +BOOT_NO_PIE_FLAG   := `case ${host} in *-*-darwin[1-9][1-9]*) echo
 -Wl,-no_pie ;; esac;`
 }}}
