I'm very sure I used 2.16.1 with the patch to linux.h.

(build/mipsel-unknown-linux-gnu/gcc-3.3.4-glibc-2.3.2/gcc-3.3.4/gcc/config/mips/linux.h)

Sigh... tried this as well (binutils/gas/config/tc-mips.[ch]).  Same 
thing, still bloated:

hello.3.3.4:     file format elf32-little
hello.3.3.4
architecture: UNKNOWN!, flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED

compilers above major number 3.)  :-)
