Joseph Myers enhanced glibc.spec so that we no longer need the separate
glibc32 source package which its tarball of pre-built glibc binaries.
As part of the DNF5 adjustment to the removal of filelists, I believe
some reverse dependencies (including gcc) have been adjusted to use the
package name explicitly, as in:
%ifarch x86_64
BuildRequires: (glibc32 or glibc-devel(%{__isa_name}-32))
%endif
Most packages have dropped the glibc32 dependency because it was
unneeded (or should do so).
This new package only contains the glibc files needed to build gcc.
Other shared objects, such as libcrypt.so.2 or libgcc_s.so.1, are no
longer included.
There is a pungi configuration which is expected to filter out glibc32
from the compose. We'll see how that works out. The new glibc32
package does not have any ELF dependency information, so the risk of it
being installed by accident is reduced compared to the old one.
Once we have a compose without glibc32, I will retire the glibc32 source
package because we no longer need it. Currently, glibc32 is still
tagged in, but it has a lower version than the glibc-built package, so
the latter is installed in the buildroot.
Thanks,
Florian
