In fact my tests was in a virtual machine.
I restarted the compilation of GCC from scratch, directly
on my machine (x86_64) and the result is slightly different,
but almost the same:

By curiosity, I tried to replace "toreset(__spin_table_addr)"
by "0xfffffffffffff144" and it works... but it's not a
solution.

I use the last version of U-Boot from the git branch 'master'.

Here is my configuration for GCC:

export PATH=/home/arzel/cross_compile/tools/bin:$PATH

Binutils (v2.23.2)

configure --target=powerpc-e500v2-linux-gnuspe \
  --prefix=/home/arzel/cross_compile/tools \
  --with-sysroot=/home/home/arzel/cross_compile/sysroot \
  --disable-nls --disable-multilib

make all
make install

GCC (v4.8.0)

configure --target=powerpc-e500v2-linux-gnuspe \
  --prefix=/home/arzel/cross_compile/tools \
  --with-sysroot=/home/arzel/cross_compile/sysroot \
  --without-headers --with-newlib --disable-shared \
  --disable-threads --enable-languages=c \
  --disable-decimal-float --disable-__cxa_atexit \
  --disable-libquadmath --disable-libssp \
  --disable-libgomp --disable-libmudflap \
  --disable-nls --disable-multilib \
  --enable-e500_double --with-long-double-128 \
  --with-cpu=8548

make all-host all-target-libgcc
make install-host install-target-libgcc

Normally, I can build U-Boot with this small GCC.
