This adds softfloat support to GOARM, as proposed here: https://github.com/golang/go/issues/61588 This is similar to https://github.com/tinygo-org/tinygo/pull/4189 but with a few differences: * It is based on the work to support MIPS softfloat. * It fixes the issue that the default changed to softfloat everywhere. This PR defaults to softfloat on ARMv5 and hardfloat on ARMv6 and ARMv7. * It also compiles the C libraries (compiler-rt, musl) using the same soft/hard floating point support. This is important because otherwise a GOARM=7,softfloat binary could still contain hardware floating point instructions.
