 It fails with:

mipsel-linux-gcc -nostdlib -nostartfiles -r -o librtld.os '-Wl,-('
dl-allobjs.os ../libc_pic.a -lgcc '-Wl,-)'

because librtld.os includes a definition of __libc_multiple_libcs
(originating from sysdeps/generic/dl-sysdep.c) and ../libc_pic.a includes
another one (from sysdeps/unix/sysv/linux/init-first.c).  Init-first.c
gets pulled in because nothing else provides either __libc_argc or
__libc_argv and these symbols are used by elf/dl-open.c (the code of which
is included in librtld.os).
