When I fixed one of my packages (libhocr), I chose a different fix:
* Added: BuildRequires: autoconf, automake, libtool, pkgconfig
* In "%prep" added: autoreconf --install --force
IMO this is better then the new rpm kludge:
* In autotools based projects, the tarball contain *many* generated files.
(e.g: configure, config.h.in, config.{guess,sub}, INSTALL, etc.}
* The only reason they are in the tarball is to enable build without
the autotools suite (e.g: on other platforms)
* As such, these files are not [and should not be] committed to version
control systems.
* So although they are packages in the source tarball, they are no
part of the package real "source" -- they just happen to
come from the platform of the one who maintain the source tarball.
(via "make dist")
* The "autoreconf" solution let autotools handle this complete problem
without trying to mess in its internals (rpm replacing only some files).
* As an example how wrong it is for rpm macros to interfere with the
internal logic of autotools, you could have a look in %GNUconfigure
macro in /usr/lib/rpm/macros. This one, tries to second guess
autoconf behavior, but it still search for "configure.in" files.
(For those who don't know -- while these files are still supported,
most modern packages correctly renamed them to "configure.ac").
In the Fedora spirit of "everything buildable from clean sources", I think
the "autoreconf" solution should be globally adopted (regardless of aarch64):
* It doesn't use generated files as input to the build process.
* It delegates the actual management to where it belongs.
