With this change, it is possible to compile ./testdata/float.go for the
ESP8266 and run it successfully. Previously it would result in many
linker error like this:
/tmp/tinygo494494333/main.o:(.literal.runtime.printfloat64+0x0): undefined reference to `__unorddf2'
/tmp/tinygo494494333/main.o:(.literal.runtime.printfloat64+0x4): undefined reference to `__gtdf2'
/tmp/tinygo494494333/main.o:(.literal.runtime.printfloat64+0xc): undefined reference to `__nedf2'
/tmp/tinygo494494333/main.o:(.literal.runtime.printfloat64+0x10): undefined reference to `__ltdf2'
/tmp/tinygo494494333/main.o:(.literal.runtime.printfloat64+0x1c): undefined reference to `__gedf2'
I have verified that the output on the serial console matches
./testdata/float.txt when run on the ESP8266.
