Anton Blanchard 7e60d1b427 [POWERPC] Move ELF_ET_DYN_BASE up to 512MB point 
I often test new versions of glibc by doing:

LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary>

One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded
at 0x8000000 (128MB) with the heap right after it. Since we normally
link binaries at 0x10000000 (256MB) we only had about 128MB of space for
the heap:

00100000-00103000 r-xp 00100000 00:00 0           [vdso]
08000000-0801e000 r-xp 00000000 00:01 33079       /lib/ld-2.5.so
0802d000-0802f000 rwxp 0001d000 00:01 33079       /lib/ld-2.5.so
0802f000-08050000 rwxp 0802f000 00:00 0           [heap]
0fe91000-0ffd9000 r-xp 00000000 00:01 33082       /lib/libc-2.5.so
0ffd9000-0ffe8000 ---p 00148000 00:01 33082       /lib/libc-2.5.so
0ffe8000-0ffea000 r--p 00147000 00:01 33082       /lib/libc-2.5.so
0ffea000-0ffed000 rwxp 00149000 00:01 33082       /lib/libc-2.5.so
10000000-10004000 r-xp 00000000 00:01 76          /bin/sleep
10013000-10014000 rwxp 00003000 00:01 76          /bin/sleep
ffb41000-ffb56000 rw-p ffb41000 00:00 0           [stack]

One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000.
This allows 128MB for the binary (hopefully enough for even the most
crazy c++ apps), and with our current layout we will grow the heap up
and the stack down, allowing potentially gigabytes of heap:

00100000-00103000 r-xp 00100000 00:00 0           [vdso]
