esp: add picolibc
With this change, it is possible to fully use CGo on ESP32/ESP8266
chips. The following will work:
tinygo flash -target=d1mini -port=/dev/ttyUSB0 ./testdata/cgo/
tinygo flash -target=esp32-mini32 -port=/dev/ttyUSB0 ./testdata/cgo/
Previously it would produce output like the following:
/tmp/tinygo905539688/main.o:(.literal.runtime.run$1$gowrapper+0x150): undefined reference to `strcpy'
/tmp/tinygo905539688/main.o:(.literal.runtime.run$1$gowrapper+0x154): undefined reference to `strlen'
