LibreSSL/OpenSSL should be compiled as a position-independent library
(i.e. with -fPIC) otherwise OpenSSH will not be able to link with it.
NB. If you operating system supports /dev/random, you should configure
libcrypto (LibreSSL/OpenSSL) to use it. OpenSSH relies on libcrypto's
-direct support of /dev/random, or failing that, either prngd or egd

PRNGD:
If your system lacks kernel-based random collection, the use of Lutz
-Jaenicke's PRNGd is recommended.

EGD:
-If the kernel lacks /dev/random the Entropy Gathering Daemon (EGD) is
-supported only if libcrypto supports it.
