Build: Bump all toolchains to GCC 4.9.4 + Binutils 2.26.1

Browse source 
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)
