Adding the attached patches to meta-pkgs/boost/patches/ fixes this issue for
me. But then I run in another problem with exceptions (port-arm/52509).
Maybe we should default to a vfp3 FPU when configuring the compiler for
earmv6hf or earmv7hf targets ?

BTW, AFAIK vfpv4 has more FP registers than vfpv3. Does anyone known if
boost's context library is complete for vfpv3 or vfpv4 FPUs ?
