* Use newlib libc library This change adds libcmin.a, which is created from newlib libc by selectively removing some of the object files (mostly related to heap management). The list of files is available in tools/sdk/lib/make_libcmin.sh. Files which are not needed are commented out. This change adds support for various functions which were missing, like sscanf, strftime, etc. * Fix some of the time functions * Redirect stdout to serial * Implement __putc_r * Switch to custom newlib build Built from https://github.com/igrr/newlib-xtensa using: ./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 --enable-newlib-nano-formatted-io --enable-newlib-reent-small --prefix=path-to-arduino-core/tools/sdk/libc CROSS_CFLAGS="-DMALLOC_PROVIDED -DSIGNAL_PROVIDED -DABORT_PROVIDED" make make install * Update tests
