Recent changes to i386, most probably the virtual memory mappings and associated mode bits but possibly other things, breaks compiling.

Setting: # paxctl +m /usr/libexec/cc1 allows compilation to succeed, albeit the the "text relocations" warning remains. The resulting binary works. -- |/"\ John D.
