|  37ee4bea40 This reduces binary size substantially, for two reasons:
  - It switches to a much more architecture ARMv4 vs ARMv7.
  - It switches to Thumb2, which is a lot denser than regular ARM.
Practically all modern and not-so-modern ARM chips support Thumb2, so
this seems like a safe change to me.
The size in numbers:
  - Code size for testdata/stdlib.go is reduced by about 35%.
  - Binary size for testdata/stdlib.go (when compiling with -no-debug to
    strip debug information) is reduced by about 16%. | ||
