GCC 4.9.4 was already used for MIPS and all hosted targets; this enables it across the board for everything (ie m68k and arm native) Other changes: * Use '-Os' as the default optiomization for all targets (was only disabled for arm native) * Enable -funit-at-a-time and -Wextra * Drop all obsolete toolchain patches * Update ARM multilib/exception patch * Bump toolchain libs (gmp, mpfr, mpc) to recommended versions, and add 'isl' to enable better optimization & vectorization opportunities. (Will revisit optimization for the codecs and plugins at a later date) Confirmed working: * armv4t (ipodmini2g and many other PP502x targets) * arm >= v5 (sansaclipplus, ipod6g, ipodnano2g, sansafuzeplus) * m68k (ihp100) Change-Id: If9ed405ae0f289d9adea46d4cf46bfefc2f4250d
