The la macro is split into a lui and a daddiu. The daddiu is not correct 
for a mips32 cpu. Getting rid of the -mcpu=4600 fixes the problem and 
the daddiu is then changed addiu.

This is IIRC a known bug in at least current binutils CVS, a patch
to fix it really was already discussed.

Is this macro expaned by the compiler or assembler?  Just -mcpu=r4600
should not make cc1 generate any instructions beyond MIPS I.

In the past we already had inline assembler fragments that left the assembler
in .misp3 mode thus resulting the rest of the file bein assembled in
mips3 mode.

Is there a truly correct -mcpu option for a mips32 cpu?

None is really good, none is really bad ...

In theory, no -mcpu option (which is to be deprecated in
favor of -march/-mtune) and -mips32 as ISA flag _should_ work.

In practice, the patch which adds this to gas was discussed on the
binutils list the last days and is likely to go in CVS
today or tomorrow.
