Upstream is not very helpful "We don't support LibreSSL". Could you
perhaps participate to the bug report to say Buildroot is also
interested in seeing LibreSSL supported by Qt ?

Why are you patching only the 5.11.1 version, and not also the LTS
version ?

I don't have the full code context here, but isn't this going to #error
when using LibreSSL, because defined(LIBRESSL_VERSION_NUMBER) is true ?

Why not && !defined(LIBRESSL_VERSION_NUMBER)

like is done in the previous chunk, and the next one ?
