Subject: [PATCH] fix link issues with clang and --as-needed
> ld.lld: error: undefined reference: EVP_MD_CTX_new
> >>> referenced by ../lib/libipv6calc.so.4.3.2
> ./ipv6calc: symbol lookup error:
> ../databases/lib/libipv6calc_db_wrapper.so.4.3.2: undefined symbol: log2
add MD5_LIB for libmd/openssl
add EXTDB_LIB where IPV6CALC_LIB is called
move extern math in LIBS instead of LDFLAGS
