Compile and link the attached C program as follows. I used gcc-4.1.1 and
binutils-2.17, but gcc >= 4.0.0 and binutils >= 2.16 probably suffice.

 # gcc -fpic -o test.o -c test.c
 # ld -Ttext 100000000 -o test test.o

Disassembly of the result trivially shows that the address of weak symbol
'x' is 0x100000000.
