Subject: [PATCH 1/2] configure: fix AC_CHECK_FUNCS(EVP_sha224 EVP_sha384 ...)
 failure on static linking

If building as static lib, AC_CHECK_FUNCS(EVP_sha224 EVP_sha384 ...)
fails due to missing -lz in $LIBS.
At the moment, $LIBS contains $LIBCRYPTO only discarding previous $LIBS
content.

Add $LIBS to:
LIBS="$LIBCRYPTO"
as:
LIBS="$LIBCRYPTO $LIBS"
This way $LIBS will contain -lz at the end of linking command that in
static linking build is mandatory.
