buildsystem: fix for cross-compilation

Avoid running the openssl binary, since it would break for
cross-compilation. Buildroot has a supported version, anyway.

Also, avoid adding hard-coded includes and libraries search
paths, since they are missing the destdir; Buildroot compilers
and linkers already know where to search, anyway.
