I'll assume you mean the headers in bionic/libc/kernel which are derived from external/kernel-headers. These headers are updated on an "as needed" basis only. The process is:
When there is a need, copy in only the necessary updated headers from kernel to external/kernel-headers/original. Run the scripts described in bionic/libc/kernel/README.txt. This generates derived headers under bionic/libc/kernel. Important things to note are that (a) it's only done as needed, and (b) only a subset of the headers are part of NDK, and the rest might be used internally by parts of the platform but aren't a stable API. So in the particular case you mention, if those headers haven't been updated in a while, it means there wasn't a need yet. For more details and rationale, refer to that README.txt in bionic.
