[OE-core] [PATCH 0/5] Support for "baremetal" toolchains

[Juro Bystricky]

These patches allow building "baremetal" images, in particular
"baremetal" cross-compilers. The cross-compilers make no assumtions about
target OS and come with no "C" libraries.  

I tested the patches with the following in local.conf:

PACKAGE_CLASSES="package_ipk"
SDKMACHINE="i686" 
TCLIBC="baremetal"
 
MACHINE="qemuarm" 
MACHINE="qemux86"
 
GCCVERSION="5.2.0"  
GCCVERSION="4.9.3" 
 
The patches are based on the original work by Richard Purdie.

Juro Bystricky (5):
  tclibc-baremetal.inc: baremetal specific distro policy file
  gcc-cross-canadian.inc: overrides for libc-baremetal
  gcc-cross.inc: overrides for libc-baremetal
  libgcc-common.inc: overrides for libc-baremetal
  cross-canadian.bbclass: support for TCLIBC="baremetal"
