Newlib's malloc() uses too much .data (~ 2 KiB) #9

                0x0000000020000060      0x408 /usr/bin/../lib/gcc/arm-none-eabi/5.3.1/../../../../arm-none- .data.impure_data

Swap this malloc for something less greedy. Specifically, this blocks porting to ARMv6-M platforms (micro:bit has 16 KiB SRAM for instance).
