    Support FreeBSD's API for querying the ELF aux vector.
    
    We use this for detecting the Arm crypto extension and using it to
    enable accelerated AES and/or SHA-{1,2}. Previously, I had code that
    called glibc's getauxval(3) function, conditioned on #ifdef __linux__.
    Now, instead, I do an autoconf test to query the presence of getauxval
    itself (so that any other system with the same API can still work),
    and alongside it, also check for the analogous FreeBSD libc function
    elf_aux_info(3). As a result, building on Arm FreeBSD now gets the
    accelerated-crypto autodetection.
