I'm not sure if it's the _same_ problem, since building shared libs with
build.sh+latest tools worked for me.  In fact, that + scp allowed me to
fix the problem I was originally interested in fixing

Also, the assembly for my case looks a little different:

broken (cc):
    b034:       7f c8 02 a6     mflr    r30
    b038:       93 01 00 30     stw     r24,48(r1)
    b03c:       90 01 00 54     stw     r0,84(r1)
    b040:       83 1e 80 d0     lwz     r24,-32560(r30) <- boom
works (build.sh):
    b9b4:       7f c8 02 a6     mflr    r30
    b9b8:       93 01 00 30     stw     r24,48(r1)
    b9bc:       90 01 00 54     stw     r0,84(r1)
    b9c0:       3f de 00 02     addis   r30,r30,2
    b9c4:       92 e1 00 2c     stw     r23,44(r1)
    b9c8:       3b de 9f 08     addi    r30,r30,-24824
    b9cc:       93 21 00 34     stw     r25,52(r1)
    b9d0:       83 1e 80 d0     lwz     r24,-32560(r30)


Might be related, though ;)
