If you want to use installed version, use:

./configure --with-cc-opt="-I /path/to/include" --with-ld-opt="-L /path/to/lib"

These options are used to build OpenSSL library from sources.  
Additional options are passed to OpenSSL's ./config.

Either you don't have OpenSSL sources in /usr/local/src/openssl/ 
or they are corrupted somehow.  Vanilla OpenSSL 1.0.0 sources do 
have Makefile with target 'clean', try re-extracting them (if you 
really want nginx to build them instead of using already installed 
version).

nginx do honor CFLAGS (use -r in grep, it helps), but not LDFLAGS.

See above.
