PowerPC64: Report overflow on @h and @ha relocations
This patch updates glibc in accordance with the binutils patch checked in here: https://sourceware.org/ml/binutils/2013-10/msg00372.html This changes the various R_PPC64_..._HI and _HA relocations to report 32-bit overflows. The motivation is that existing uses of @h / @ha are to build up 32-bit offsets (for the "medium model" TOC access that GCC now defaults to), and we'd really like to see failures at link / load time rather than silent truncations. For those rare cases where a modifier is needed to build up a 64-bit constant, new relocations _HIGH / _HIGHA are supported. The patch also fixes a bug in overflow checking for the R_PPC64_ADDR30 and R_PPC64_ADDR32 relocations.
