The files you are looking for are in the libssl1.0.0 and libssl-dev libraries:

spyked at tuvok:~% apt-file search opensslconf.h
libcyassl-dev: /usr/include/cyassl/openssl/opensslconf.h
libssl-dev: /usr/include/x86_64-linux-gnu/openssl/opensslconf.h

(obviously you need libssl-dev:i386 if you are going to compile with m32)

spyked at tuvok:~% apt-file search libcrypto.so.1.0.0
libssl1.0.0: /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0

(same here, you need libssl1.0.0:i386)
