eagle.app.v6.common.ld is no longer distributed with esp8266 tools

[raimue]

The linker script eagle.app.v6.common.ld is no longer distributed in the esp8266 repository as of 2.4.2, but it is supposed to be generated with a recipe hook specified in platform.txt.

The ArduinoESP.mk would either need to implement generic support for recipe.hooks.linking.prelink.1.pattern or at least just run the equivalent command to generate the linker script.

One possible workarounds for other stumbling over the same problem is to check out the 2.4.1 tag of esp8266/Arduino instead of the latest version.

Some more pointers:

• Add flash for vtable destination, make it default, and add build menu to control options esp8266/Arduino#4582
• esp8266/Arduino@d582cab
• plerup/makeEspArduino@170200f (how makeEspArduino implements this)

@andreasberg Thank you for your work that allows me to use my workflow based on Arduino-Makefile for esp8266 projects!
