--enable-kernel=VERSION compile for compatibility with kernel not older than
VERSION
- --enable-all-warnings enable all useful warnings gcc can issue
--disable-werror do not build with -Werror
--enable-multi-arch enable single DSO with optimizations for multiple
architectures
--enable-memory-tagging enable memory tagging if supported by the
architecture [default=no]
- --enable-crypt build and install the legacy passphrase hashing
- library, libcrypt
- --enable-nss-crypt enable libcrypt to use nss
--enable-systemtap enable systemtap static probe points [default=no]
--disable-build-nscd disable building and installing the nscd daemon
--disable-nscd library functions will not contact the nscd daemon
