sb-perl fails on ia64 with internal compiler error

Not sure what we can do about this, I suppose I could try to strip out the
offending bits from lsb-perl. We don't actually use lsb-perl for much.

adding XS code from parts/inc/newCONSTSUB
../../miniperl "-I../../lib" "-I../../lib" ../../lib/ExtUtils/xsubpp
-noprototypes -typemap ../../lib/ExtUtils/typemap -typemap typemap
RealPPPort.xs > RealPPPort.xsc && mv RealPPPort.xsc RealPPPort.c
