Note the existing checks for ld wrap support in configure.ac, since it's
only available on GNU ld and very very recent versions of OpenSolaris ld.
It should be okay to use if configure finds it, you just can't assume that
it will be found everywhere.
ELF interposition is more widely available, but still not universal to all
our platforms.
