all: add floating point option for ARM targets
This change introduces new options to set the floating point
mode on ARM targets. The GOARM version number can optionally be
followed by ',hardfloat' or ',softfloat' to select whether to
use hardware instructions or software emulation for floating
point computations, respectively. For example,
GOARM=7,softfloat.
Previously, software floating point support was limited to
GOARM=5. With these options, software floating point is now
extended to all ARM versions, including GOARM=6 and 7. This
change also extends hardware floating point to GOARM=5.
GOARM=5 defaults to softfloat and GOARM=6 and 7 default to
hardfloat.
For #61588
