[yocto] baremetal cross-compiler

[Bystricky, Juro]

sorry for the late reply, somehow this mail fell through the cracks.
Indeed, setting TCLIBC="baremetal" is all you should need to do.

FWIW, I use these values in my local.conf:

MACHINE = "qemuarm"
TCLIBC = "baremetal"
TUNE_FEATURES = "armv7m cortexm3" 
PACKAGE_CLASSES = "package_ipk"
bitbake meta-toolchain
