binutils/binutils: added 2.21.53 snapshot

binutils 2.21 doesn't recognise the Cortex-M3 SVC instruction when
assembling with -mcpu=all. This was fixed by the 2.21.53 snapshot and
is needed to build RTOSs such as FreeRTOS.

     4 Shut off a stupid warning: preffered-stack-boundary must be between 4 ad 12,

     5 and 2 is not.
