To save you some iterations on looking for missing functions, recommend using this "minimal" set of components:
app_trace app_update bootloader bootloader_support cxx driver efuse esp32s2 esp_common esp_eth esp_event esp_netif esp_ringbuf esp_rom esp_system esp_timer esp_wifi espcoredump esptool_py freertos heap log lwip mbedtls newlib nvs_flash partition_table perfmon pthread soc spi_flash tcpip_adapter vfs wpa_supplicant xtensa

answering the question from the livestream: we need to "undefine" functions so that the linker needs to look for them in the static libraries.
If the linker encounters an object file inside a static library, and the object file doesn't resolve any of the undefined references, then the object file is discarded. So we add these -u flags so that linker looks into the archives and includes the object files we want.

asan considers that memcmp(p, q, N) is permitted to access N bytes at each
of p and q, even for values of p and q that have a difference earlier.
Accessing additional values is frequently done in practice, reading 4 or
more bytes from each input at a time for efficiency, so when completing
"non_exist<TAB>" in the repl, this causes a diagnostic:

Don't merge this if you don't wish to...it's not 100% clean code. But I wanted to do a PR so you could see the changes.
It still doesn't build yet...but it's progress!
