The auto linking is globally controlled with the --with-openssl cofigure option, but you could build sort (and md5sum) without that dependency with: ./configure ac_cv_lib_crypto_MD5=no
Thanks, I was thinking more along the lines that Bruno suggested, which to continue to link to libcrypto, but do it with dlopen/dlsym in 'sort' only when need_random is true.
It's not clear to me offhand whether this should be done entirely in Coreutils, or whether we should add some Gnulib support to make it easier to do this sort of lazier linking.
Also, why doesn't coreutils/configure's ---with-linux-crypto option cause 'sort' to use Linux kernel crypto? Is this because the syscall overhead would be too high and it's significantly faster to do it in user space?
I naively thought that --with-linux-crypto would mean we wouldn't need to link to libcrypto. Evidently not.....
