When we build with newlib enabled and utilizing one of the other
variants (like having floating point enabled) we need to have the proper
library path setup to find the library. This is mimicked after what we
do in Makefile.toolchain.zephyr for newlib.

We default DTC to /usr/bin/dtc so we can build targets that are using
devicetree and not using the zephyr SDK (which provides a version of
dtc).

Utilize the gcc -print-libgcc-file-name to determine the path to
libgcc.a. Using this also resolve issues if we are building with
floating point and the various ABIs to pickup the right lib.
We can also simply a few Makefiles and remove the need to export
_CROSS_COMPILE_arm_isa.

We need to expose the path to the newlib headers that are part of the
ARM embedded gcc at ${GCCARMEMB_TOOLCHAIN_PATH}/arm-none-eabi/include
otherwise we get build errors like when trying to use newlib:
lib/libc/newlib/libc-hooks.c:17:19: fatal error: errno.h: No such file or directory

for GCC ARM Embedded
When compiling and linking Zephyr with GCC ARM Embedded,
the path to the libraries to be linked needs to be provided
explicitely for the correct variant to be linked in.
