autoconfreconfigure timestamp -> restarting build

[rhubert]

[End    387] NOTE: CHECKOUT  core::dbus-tgt - dev/src/core/dbus/1/workspace (initial checkout) 
[***** ****] WARN: Restart build due to wrongly predicted sources.

This is caused by autoreconf timestamping some files, e.g.: aminclude_static.am

# aminclude_static.am generated automatically by Autoconf                                                                                              
# from AX_AM_MACROS_STATIC on Wed Mar 12 18:12:03 UTC 2025

Where date is called in https://gitlab.freedesktop.org/dbus/dbus/-/blob/dbus-1.15.8/m4/ax_am_macros_static.m4?ref_type=tags#L36

I'm unsure how to handle this. For dbus it might be easy as from dbus-1.16 they dropped autotools, but there might be more like this?

Maybe a more generic solution would be to use libfaketime for autoreconf & friends?

Somehow working prototype: rhubert/basement@ab59ba5

Thanks for tracking this down.

I'm afraid the only safe option is to fix such error one-by-one. Using an absolute timestamp in libfaketime is even officially discouraged. It will probably break scripts and tools in interesting ways. I find the risk higher than tracking down such nuisances individually.

Having said that, I've prepared BobBuildTool/bob#623 to really halt the build on such error.
