Remove HPUX

IIUC it is a pre-requisite for IPv6 support, some UNICes do not support
getaddrinfo required for IPv6.  But coincidentally such UNICes are no longer
really supported by GDB.  Therefore it was concluded we can remove all such
UNICes and then we can implement IPv6 easily with getaddrinfo.
