Let the standard library think that it is compiling for js/wasm. The most correct way of supporting bare metal Cortex-M targets would be using the 'arm' build tag and specifying no OS or an 'undefined' OS (perhaps GOOS=noos?). However, there is no build tag for specifying no OS at all, the closest possible is GOOS=js which makes very few assumptions. Sadly GOOS=js also makes some assumptions: it assumes to be running with GOARCH=wasm. This would not be such a problem, just add js, wasm and arm as build tags. However, having two GOARCH build tags leads to an error in internal/cpu: it defines variables for both architectures which then conflict. To work around these problems, the 'arm' target has been renamed to 'tinygo.arm', which should work around these problems. In the future, a GOOS=noos (or similar) should be added which can work with any architecture and doesn't implement OS-specific stuff.
