gcc-4.5: Backport with-linker-hash-style and backports from FSF & linaro
backport --with-linker-hash-style from trunk, fix GNU_HASH QA warnings once for all Explicitly disable configuring with cloog/ppl while building gcc if the user has it installed on build box then gcc's configure will try to use it and it can go wrong and create problems since we never built it so Move to tip of FSF gcc-4_5-branch brings in bug fixes PR 50091/ppc 50464/x86 50273/fortran 44473/c++ mangler 49965/sparc 50565/c 50659/fortran 50618/c++ 50737/alpha 50793/c++ 50788/x86/SSE 50691/pa 50875/x86/SSE 50979/sparc 30282/ppc 51187/rtl 50888/bootstrap 48190/debug/QEMUhog Merge fix for LP689887/linaro https://bugs.launchpad.net/gcc-linaro/+bug/689887 Signed-off-by: Khem Raj <raj.khem@gmail.com>
