gdbserver: Ensure AT_HWCAP2 is defined 

When using older compilers, AT_HWCAP2 may not be be defined.
It is defined in elf/common.h, however including this in
gdbserver/linux-low.c causes conflicts.

Manually add the define if it does not exist.

gdb/gdbserver/ChangeLog:

	* linux-low.c (AT_HWCAP2): Add define if not already included.
