Error in creating ESP8266 Firmware

Just checked, and as you suggest, it's this commit: https://github.com/espruino/Espruino/com­mit/9781bacee8185b58438604cb22672389bc3f­f42d

Extremely frustrating as the 'built-in' maths functions that were removed were pretty bad, and doing the removal has actually improved the situation on pretty much all platforms.

@tve do you have any ideas how this could be fixed? I increased the size of iram1_0_seg in the linker so it builds, then grabbed these out of the listing:

So it looks like the 3 biggest functions are maths ones, which potentially could be excluded from iram (somehow??).
