package/proftpd: prevent openssl pthread detection
The proftpd configure script doesn't use pkg-config to detect openssl libraries. Instead, it just adds -lcrypto. Since openssl may be linked with pthread, it tries to detect that by calling 'openssl version -f', which gives the arguments with which openssl was compiled. Since the openssl executable used is either host-openssl or the system installed openssl, the output of 'openssl version -f' is useless in Buildroot context. If the target toolchain doesn't have threads support, it will wrongly pick up -pthread from host-openssl. Fortunately there is a simple workaround: --without-openssl-cmdline says that there is no openssl executable and skips the test, so -pthread is not added. It turns out -pthread is never needed, even in static linking cases, because openssl/libressl puts the thread support in a separate object file that only gets linked in if the program actually uses threads (which proftpd doesn't).
