We need to compile nativesdk components as well as nativesdk-glibc using this
defined to 2.6.32 as well. otherwise it will have wrong assumptions about
system calls available to it during build ( 3.14 ) vs at runtime ( 2.6.32 ) and
many nativesdk programs could fail to run properly. Please note that 2.22 needs
2.6.32
can’t go below that.
