 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 ?
