newlib: Adds newlib and libgloss recipes

Newlib is a C library that is intended to be used on embedded systems.
It is a conglomeration of several library parts, all under free software
licenses that make them easily usable on embedded products.

Newlib provides a C library alternative that can run on baremetal, mainly
for resource constrained devices.

Libgloss is the BSP part of the C library, which can be easily modified
to port for new hardware platforms.

+Make install tries to perform install for all variants, but some of them use the same
+name for crt0 in specific, so performing all of them results in an error during
+do_install, we simply modify the name of the objects so the installation can proceed
+and leave it to the user to select which object files to use.

+Upstream-Status: Inappropriate  [OE-Specific]
+
+When trying to build libgloss for an arm target, the build system
+complains about missing some include files:
+
+| fatal error: acle-compiat.h: No such file or directory
+|  #include "acle-compat.h"
+|           ^~~~~~~~~~~~~~~
+| compilation terminated.
+
+These include files come from the newlib source, but since we
+are building libgloss separately from newlib, libgloss is unaware
+of where they are, this patch fixes the INCLUDES so the build system
+can find such files.
