Enabled by default, set PRINTF_SCANF_FLOAT_SUPPORT=0 in local.mk/Makefile to disable
newlib-xtensa revision ae10be3
Configure/compile steps:
../configure --with-newlib --enable-multilib
--disable-newlib-io-c99-formats --enable-newlib-supplied-syscalls --enable-target-optspace --program-transform-name="s&^&xtensa-lx106-elf-&" --disable-option-checking --with-target-subdir=xtensa-lx106-elf
--target=xtensa-lx106-elf --prefix=/home/gus/dev/esp/rtos/open-rtos/libc/ --enable-newlib-nano-malloc --enable-newlib-nano-formatted-io --enable-newlib-reent-small --prefix=path_to/esp-open-rtos/libc
CROSS_CFLAGS="-DSIGNAL_PROVIDED -DABORT_PROVIDED" make
