[GOLD, PowerPC64] Debug info relocation overflow
It is possible to build huge binaries on powerpc64, where 32-bit
addresses in debug info are insufficient to descibe locations in the
binary. Help out the user, and only warn about debug overflows.
* powerpc.cc (Target_powerpc::Relocate::relocate): Warn on
relocation overflows in debug info.
(cherry picked from commit 03c02b696e90714a0ae2c0200d3c65cfffcaa1ee)
