It turns out that a bug has already been filed in relation to the error.
https://bugzilla.mozilla.org/show_bug.cgi?id=576764#c1

chromium_types.h defines "_ppc_" as lowercase when in fact it should be
uppercase "_PPC_" or "_powerpc_" I changed the #define in the file to
read "_PPC_" and it buit successfully as described by the submitter -

Happy Days :-)

I'm afraid PPC assembler is way beyond my reach :-) Thankfully it
appears to be small bug as such with a simple fix.
