On MIPS clang default to different arch than GNU

clang -cc1 version 3.8.0 based upon LLVM 3.8.0svn default target

-msoft-float -KPIC -o conftest /tmp/foo-3da0d2.s
address@hidden:~/src/llvm/tools/clang> file conftest 
conftest: ELF 32-bit MSB relocatable, MIPS, MIPS32 rel2 version 1 (SYSV), not 
stripped

While for the same file GAS creates

address@hidden:~/build/grub> mips-suse-linux-as -v asm-tests/mips.S 
GNU assembler version 2.24.0 (mips-suse-linux) using BFD version (GNU Binutils; 
openSUSE 13.2) 2.24.0.20140403-6.1
address@hidden:~/build/grub> file a.out 
a.out: ELF 32-bit MSB relocatable, MIPS, MIPS-I version 1 (SYSV), not stripped
address@hidden:~/build/grub> 

(using -integrated-as does not change it - arch is still the same).

Not sure if it matters.
