[Buildroot] [PATCH 04/15] package/pkg-generic.mk: Fix .la files overwrite detection

[Yann E. MORIN <yann.morin.1998@free.fr>]

On 2021-06-21 16:11 +0200, Herve Codina spake thusly:
> During per-package build, original .la files are modified by
> fixup-libtool-files calls.
> But since fixup-libtool-files modifies files using sed --in-place,
> these modification are done using a temporary file and a call to
> rename. Rename breaks the hardlink to the original file and leave the
> temporary file in per-package TARGET dir.
> As the original file is not modified, this is no longer considered as
> an overwrite.
> 
> To fix this detection, this patch simply considers the what is done
> by fixup-libtool-files is part of the original snapshot used to
> detect overwrites. And so, the original snapshot is taken after
> fixup-libtool-files call.

Then this should be squashed together with the first patch, to avoid
introducing the issue just to fix it a few patches down the series.

You should however add a note about that in the commit log of the first
patch, of course, to explain why the overwrite ifnra is inserted after
the .la tweaks.

So, I agree with the explanations, which make sense, but I disagree that
it should be a separate patch...

Yann E. MORIN.
