While I cannot speak for gdb requirements, I can say
that there is no requirement in generic-SYSV that shared
objects start at a zero address.
SGI IRIX (which is SYSV based) has never used zero as the base
address for shared objects, but always pre-assigns a non-zero
base address at static link time (intending that the shared
object will start up faster if it can run at that address).
