Linker script generator produces build/esp32/esp32.common.ld from components/esp32/ld/esp32.common.ld.in This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and doesn't track build/esp32/esp32.common.ld at all. At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the linker script generated .ld file, which causes mis-builds. As reported on forums: https://esp32.com/viewtopic.php?f=13&t=9684&p=40105
