Yes it is!  This is some more information which gdb yields
when I run ld directly...

This is what I ran through gdb:
-------------------------------

mips-unknown-linux-gnu-ld --eh-frame-hdr -EB -dynamic-linker
/lib/ld.so.1 -o
/usr/local/src/glibc-stage1/elf/librtld.map.o -r
-L/usr/mips-unknown-linux-gnu/lib/gcc-lib/mips-unknown-linux-gnu/3.2.3 

-L/usr/mips-unknown-linux-gnu/lib/gcc-lib/mips-unknown-linux-gnu/3.2.3/../../../../mips-unknown-linux-gnu/lib 

--start-group
/usr/local/src/glibc-stage1/elf/dl-allobjs.os
/usr/local/src/glibc-stage1/libc_pic.a -lgcc --end-group
-Map /usr/local/src/glibc-stage1/elf/librtld.mapT

GDB Results (using -gdwarf2 -g3 for binutils build):
