libraries/libldap/util-int.c makes a call to hp_strerror() rather than using
HSTRERROR. This causes and unresolved symbol error on Solaris 2.6:
  Undefined                       first referenced
   symbol                             in file
  hp_strerror                         ./.libs/libldap.so
  ld: fatal: Symbol referencing errors. No output written to .libs/apitest
