Patch from Al Stone to fix ia64:

The attached patch works around some compilation failures on
ia64 caused by the use of the C preprocessor ## operator, and
allows the ia64 default configuration to build again -- or, at
least get as far as an x86 build does (the current source tree
has some problems compiling because of conflicting type
declarations for __kernel_dev_t).
