Hi,

the attached patches are the backport of these 2 patches for tools/Makefile 
that allows building when OpenSSL is not at the default location. They apply 
cleanly to both to 5.4.99 and 4.19.176. Backports for older stable kernels 
will follow.

Greetings,

Eike

[PATCH 5.4/4.19 1/2] scripts: use pkg-config to locate libcrypto

[Rolf Eike Beer]

commit 2cea4a7a1885bd0c765089afc14f7ff0eb77864e upstream.

Otherwise build fails if the headers are not in the default location. While at
it also ask pkg-config for the libs, with fallback to the existing value.
