host-nodejs is configured to build openssl by using its included openssl
source code which is based on openssl 1.0.2. If host-libopenssl was
already built its header files are being picked up during host-nodejs
build, this was verified by adding debug code to
$(HOST_DIR)/include/openssl/opensslv.h.
This situation was not a problem as long as host-libopenssl was the
same version than the openssl code included in nodejs.
Some code in host-nodejs-8.11.4/src/node_crypto.cc is guarded by
#if OPENSSL_VERSION_NUMBER < 0x10100000L
to be used only with openssl 1.0.x.
This leads to problems if host-libopenssl 1.1.x was built before. Due
to the usage of its header files some code in node_crypto.cc is not
built leading to many linking errors later on, for example:
node_crypto.cc:(.text+0x1a1): undefined reference to `DH_get0_pqg'
When the nodejs package originally was added to buildroot back in
March 2013:
https://git.buildroot.net/buildroot/commit/?id=b31bc7d4387095091a109eb879464d54d37a5eab
We did not have a host-libopenssl package back then, it was added one
month later:
https://git.buildroot.net/buildroot/commit/?id=7842789cb539b6b64d61b03f5c8dbe6813f01da7
To fix the problem we use host-libopenssl for host-nodejs.
By using host-libopenssl the build time of nodejs is reduced by ~15s.
