commit: https://git.buildroot.net/buildroot/commit/?id=f8bff449e5e4f90d777b1ba9b9ca216fd47d3128
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.11.x

Fixes #10556

The --with-crypto handling in ntp only works with libopenssl, not with
libressl, where it ends up with compilation issues like:

ntp_control.c:(.text+0x64): undefined reference to `EVP_MD_CTX_new'
ntp_control.c:(.text+0x10c): undefined reference to `EVP_MD_CTX_free'
libntpd.a(ntp_crypto.o): In function `bighash':
ntp_crypto.c:(.text+0x2e8): undefined reference to `EVP_MD_CTX_new'
ntp_crypto.c:(.text+0x328): undefined reference to `EVP_MD_CTX_free'
libntpd.a(ntp_crypto.o): In function `crypto_verify':
ntp_crypto.c:(.text+0x6cc): undefined reference to `EVP_MD_CTX_new'
ntp_crypto.c:(.text+0x710): undefined reference to `EVP_MD_CTX_free'
ntp_crypto.c:(.text+0x72c): undefined reference to `EVP_MD_CTX_free'

So ensure we only pass --with-crypto when libopenssl is used.
