Re: conflicting elf definitions in system headers

My firsl attempt at writing libelf (in FreeBSD) had taken this approach
(i.e. of using headers under <sys/>).

But this turned out to be a maintenance headache  - I soon discovered that
different OSes differed in the ELF-related definitions they kept under <sys/>,
that those definitions weren't always up to date with upstream
developments, etc.

So now I am trying a different approach: of moving ELF-related definitions to
a <sys/elfdefinitions.h> file that is meant to be complete, up to date, portable
and usable by both userspace and the kernel.  The idea being that kernel
headers (e.g. <sys/exec_elf.h>) could then #include this, allowing those
headers to focus on just the functionality needed for the kernel's ELF handling.
