[Toybox] [TOYBOX][RFC] building toybox on a Yocto enviroment

[Joya Cruz, Alejandro]

I have been trying to build toybox with different LSM enviroments
unsing yocto as building tool.
the more persistant error that I got is bellow:

|DEBUG: Executing shell function do_compile
|NOTE: make -j 8 -e MAKEFLAGS= toybox_unstripped
|scripts/make.sh
|Generate headers from toys/*/*.c...
|Make generated/config.h from .config.

|Compile toybox.....

|                       ^
|compilation terminated.
|make: *** [generated/instlist] Error 1
|WARNING: exit code 1 from a shell command.

until now the solution that i have found is this.
any suggestion if this should be part of toybox or how could i
workaround this issue?

I'm using the CFLAGS to provide the temporal environment with the
libraries.
