Subject: Avoid conflicting bool definitions on Haiku

On Haiku, link.h indirectly includes stdbool.h, causing bool to be
defined to _Bool, which is incompatible with ecl's own expected
definition of int. So we just unconditionally undef bool after
including the necessary sytem headers, which is unlikely to cause much
trouble in any case.
