It doesn't (on Linux anyway, I suspect it's the same on other systems).

That said, it's already tricky to get the library path and link order 
right on all supported configurations, and I would not like to see it 
made harder by maintaing different ones for different binaries.

Georg, does this cause an actual problem?  libgen is part of the base 
OS, right?  Also, there's no noticable difference in size on Linux.

$ cat hello.c
#include <stdio.h>
int main(void) { puts("Hello, world."); }
$ gcc hello.c -lcrypto
$ ldd a.out
         libcrypto.so.4 => /lib/libcrypto.so.4 (0x40028000)
         libc.so.6 => /lib/libc.so.6 (0x4011f000)
         libdl.so.2 => /lib/libdl.so.2 (0x40246000)
         libz.so.1 => /usr/lib/libz.so.1 (0x40249000)
         /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
