[Bug c/16830] New: Including <sys/immu.h> with -mabi=n32 causes an error.

["magnus dot bergman at observer dot net" <gcc-bugzilla at gcc dot gnu dot org>]

When including <sys/immu.h> (which mozilla likes to do) the compilation halts
with the masseage: parse error before pte_t. <sys/immu.h> contains some very
low-level stuff which is ignored if the exact architecture is unknown (this is
what happens then using the native compiler). The problem is that gcc defines
"R4000" when using -mabi=n32 (not then using -mabi=32), which disables the
excusion of all the low-level stuff, but doesn't include all of it either.
The solution I can think of is either to NOT define "R4000" (which again is what
the native compiler does). Or to also define "IP20", "IP22", "IP28" or
"IPMHSIM", which would make <sys/immu.h> go through the compiler but I have no
idea if it's the correct thing to do.
