Result of first real test with split of runtime glibc 32 bits in a separate package

  With a glibc package without elf 32 binaries, and gcc libraries
also split, what holds removal of the 32 bit libc6 package in a
minimal chroot is:

# LC_ALL=C rpm -e libc6
error: Failed dependencies:
        libc.so.6 is needed by (installed) lib64ffi4-4.6.2-4.x86_64

  These should need a rebuild to link to libffi5:

# LC_ALL=C rpm -e lib64ffi4
error: Failed dependencies:
        libffi.so.4()(64bit) is needed by (installed)
lib64ORBit2_0-2.14.19-4.x86_64
        libffi.so.4()(64bit) is needed by (installed)
lib64gnome-vfs2_0-2.24.4-4.x86_64

zlib1 should follow to split elf 32, but grub would not be an
easy task to convert to 64 bit; fortunately, if switching to
grub2 it would no longer be an issue. What is holding grub2
is updating /usr/sbin/bootloader-config and the related
perl modules in drakxtools-backend to handle grub2, as well
as some good amount of tests...

  Too bad currently "urpmq --whatrequires 'libffi.so.4()(64bit)'" does
not work, so, for some extra information, in my home desktop I have
these other:

$ LC_ALL=C sudo rpm -e lib64ffi4
