 In https://github.com/p11-glue/p11-kit/issues/192#issuecomment-419363073
 Daiki Ueno comments:

   We have the following snippet in p11-kit/Makefile.am:
 ```
   libp11_kit_la_LDFLAGS = \
           -no-undefined \
           -version-info $(P11KIT_LT_RELEASE) \
           -export-symbols-regex '^C_GetFunctionList|^p11_kit_'
 ```
   which reads that only functions matching the regex should be exported.

   Are you sure that `getauxval()` is exported from libp11-kit.so (try `nm -g
   <path-to>/libp11-kit.so)?


 Possibly a pkgsrc libtool problem instead?
