Use libc from newlib (#1752)

Browse Source 
* 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

#ifndef __IEEE_BIG_ENDIAN
#ifndef __IEEE_LITTLE_ENDIAN
/* This file can define macros to choose variations of the IEEE float
format:
_FLT_LARGEST_EXPONENT_IS_NORMAL
Defined if the float format uses the largest exponent for finite
numbers rather than NaN and infinity representations. Such a
format cannot represent NaNs or infinities at all, but it's FLT_MAX
is twice the IEEE value.
_FLT_NO_DENORMALS
Defined if the float format does not support IEEE denormals. Every
float with a zero exponent is taken to be a zero representation.
??? At the moment, there are no equivalent macros above for doubles and
the macros are not fully supported by --enable-newlib-hw-fp.
__IEEE_BIG_ENDIAN
Defined if the float format is big endian. This is mutually exclusive
with __IEEE_LITTLE_ENDIAN.
__IEEE_LITTLE_ENDIAN
Defined if the float format is little endian. This is mutually exclusive
with __IEEE_BIG_ENDIAN.
Note that one of __IEEE_BIG_ENDIAN or __IEEE_LITTLE_ENDIAN must be specified for a
platform or error will occur.
__IEEE_BYTES_LITTLE_ENDIAN
This flag is used in conjunction with __IEEE_BIG_ENDIAN to describe a situation
whereby multiple words of an IEEE floating point are in big endian order, but the
words themselves are little endian with respect to the bytes.
_DOUBLE_IS_32BITS
This is used on platforms that support double by using the 32-bit IEEE
float type.
_FLOAT_ARG
This represents what type a float arg is passed as. It is used when the type is
not promoted to double.
