Subject: [PATCH] configure: Fix incorrect argument type in gcry_md_open

The gcry_md_open function expects a gcry_md_hd_t * argument,
and not a gcry_md_hd_t argument (which is also a pointer behind
the typedef).  Future compilers will likely treat this as an
error, causing the check to fail unconditionally.
