Something along those lines.

Yes, getting to it ...

oh we just symlink it to /bin/true ;) (KIDDING)
Hm, it's currently this in the specfile:
%configure --enable-elf-shlibs --enable-nls --disable-uuidd --disable-fsck \
--disable-e2initrd-helper --disable-libblkid --disable-libuuid \
--with-root-prefix=/usr
and %configure pulls in other stuff as well - let's see, here's the full cmdline:
+ ./configure --build=s390x-redhat-linux-gnu --host=s390x-redhat-linux-gnu --program-prefix= --disable-dependency-tracking --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-elf-shlibs --enable-nls --disable-uuidd --disable-fsck --disable-e2initrd-helper --disable-libblkid --disable-libuuid --with-root-prefix=/usr
