It is rare for people to want to modify the cmd arg. In general, they
really shouldn't be, but a few still do. For those who misbehave, dupe
the string locally so they can bang on it.
This adds support for "func@localentry", an expression that returns the
ELFv2 local entry point address of function "func". I've excluded
dynamic relocation support because that obviously would require glibc
changes.

Recent ppc64 Linux kernels provide a new auxv entry AT_HWCAP2,
which is currently not recognized by GDB, causing every use of
"info auxv" to show an error.
This commit adds the AT_HWCAP2 define to include/elf/common.h
and handles it in GDB.

This changes the behaviour of @h and @ha on PowerPC64 to report errors
on 32-bit overflow. The motivation for this change is that on
PowerPC64, most uses of @h and @ha modifiers and their corresponding
relocations are to build up 32-bit offsets. We'd like to know when
such offsets overflow. Only rarely do people use @h or @ha with the
high 32-bit modifiers to build a 64-bit constant. Those uses will now
need to use two new modifiers, @high and @higha, if the constant isn't
known at assembly time. For now, we won't report overflow at assembly
time..
This also fixes an error when applying some of the HIGHER and HIGHEST
relocations.

- The Mach exception/signals escaped the TARGET_ -> GDB_ prefix change
done a while ago, but there's no real reason for that. I grepped
for TARGET_EXC and fixed all found, which unsurprisingly, means
darwin-nat.c needed fixing. I think the change there is as obvious
and trivial as it can get, so I'd be quite surprised if this broke
anything there somehow.
- GDB_SIGNAL_LAST's description string was unnecessarily inconsistent
with the enum name.
