Do not build openssl documentation.
Also, split build line into several lines.
- git clone --depth 1 -b ${OPENSSL_BRANCH} https://github.com/openssl/openssl.git
- cd openssl
- git describe --always --long
- - ./config shared -d --prefix=${PREFIX} --openssldir=${PREFIX} -Wl,-rpath=${PREFIX}/lib && travis_wait make -s -j$(nproc) all && make -s install_sw
+ - ./config shared -d --prefix=${PREFIX} --openssldir=${PREFIX} -Wl,-rpath=${PREFIX}/lib
+ - travis_wait make -s -j$(nproc) build_sw
+ - make -s install_sw
- cd ..
