With TARGET_FPU set to "softfp" stdlib-rs fails with:
error: Error loading target specification: ARM targets must specify their float ABI. Run `rustc --print target-list` for a list of built-in targets

This fpu type is set for example for arm in file
meta/conf/machine/include/arm/feature-arm-vfp.inc
when TUNE_FEATURES do not contain "callconvention-hard",
e.g. when using tune
DEFAULTTUNE = "cortexa8"
