Prevent the native(sdk) sysroot path from leaking into configargs.h. The configargs.h header is intended to be static and unchanged as the content is used as a means of determining that a gcc plugin is built for the same gcc. This also effects the output of 'gcc --version'. Due to per recipe sysroots and staging, the sysroot path would be replaced with the sysroot local to the recipe thus changing the content of configargs.h. The sysroot path is replaced with a generic "/host" prefix which represents the host sysroot (e.g. native or nativesdk).

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
