It is better to use environment variables (GOOS and GOARCH) for
consistency instead of providing two slightly incompatible ways. This
-target flag should only be used to specify a .json file (either
directly or in the TinyGo targets directory). Previously it was possible
to specify the LLVM target as well but that was never really fully
supported.
So:
- To specify a different OS/arch like you would in regular Go, use
GOOS and GOARCH.
- To specify a microcontroller chip or board, use the -target flag.
Also remove the old `os.Setenv` which might have had a purpose long ago
but doesn't have a purpose now.
