Update the Bootstrap Script For Newer Compiler (#109)

Remove some unneeded link, and include flags.
When using new compiler make sure to set LD_LIBRARY_PATH to the location of the libraries for the compiler.

Disabled customer engines for OpenSSL which was causing issues generating static archives, and causing curl to not include TLS/SSL support.

Added a CMake define required when building AWS C++ SDK on macOS Sierra (10.12.5).
