Yeah, libcropty's .init section probes for arm properties, with a
stupid version relying on libc providing "getauxval" (on Linux) or
not (everwhere else).

It uses a weak symbol for that, and p11-kit overrides getauxval.

Now the libcrypto call to getauxval ends in p11-kit's getauxval and that
can not handle the request and dies.

Two bugs here:

 - p11-kit should make the symbol hidden

 - libcrypto should #ifdef __linux__ (or something) the getauxval code
