libcrypto is build by openssl

openssl/1.0.2d-r0/openssl-1.0.2d$ ls -la  libcrypt*
libcrypto.a
libcrypto.pc
libcrypto.so -> libcrypto.so.1.0.0
libcrypto.so.1.0.0

but in my sysroot libcrypto is located in lib NOT in usr/lib

the ntp recipe in meta-openembedded/meta-networking/recipes-support/ntp/ntp_4.2.8p4.bb
defines:

 --with-openssl-libdir=${STAGING_LIBDIR}

I assume I need ${STAGING_BASELIBDIR} here instead. But currently I fail
with overwriting this in my bbappend file.

If I use EXTRA_OECONF to overwrite it in my bbappend I see two --with-openssl-libdir
statements while configuring. The first with /lib the second one with /usr/lib. 

EXTRA_OECONF  += "\
		--with-openssl \
		--with-openssl-libdir=${STAGING_BASELIBDIR} \
		--with-openssl-incdir=${STAGING_INCDIR} \
		--with-crypto \
"
