*	tclibc: For newlib and baremetal disable some security features	Nathan Rossi	2018-09-11	1	-0/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	With GCCPIE being enabled by default with security_flags.inc the compiler will by default attempt to compile and link programs as PIE. The targets that use newlib and baremetal in general do not support PIE or are otherwise unable to use it due to how embedded targets are compiled and executed. As such it makes sense to disable PIE by default for these libc's in order to prevent build failures. For baremetal tclibc there are no libc features or implementation as such there is no implementation for the strong stack protector by default.

*	tclibc-newlib: Adds a new TCLIBC variant to build with newlib as C library	Alejandro Enedino Hernandez Samaniego	2018-06-15	1	-0/+44
	This patch adds the posibility to build using TCLIBC=newlib. It allows users to build baremetal applications with the use of a C library. Newlib is a lightweight C library meant to be used on embedded systems, it is meant to be easily portable for new platforms and to provide basic functionality on them, by design, it provides stubs for some of these core functions declared as weak, so they can be built correctly and then linked against some other library which provides specifics about the platform being used if need be, libgloss takes care of these in some cases, but it can also be extended, this patch also allows the user to easily add other libraries to it by adding them to NEWLIB_EXTENDED for this specific reason.
