It turns out that there is no pre-options target hook, only a post
one, so this is what I eventually did.
I also integrated the other patches Mikael suggested, as well as
two more fixes for issues that popped up in the meantime (boost1.54
ICE, and reloction errors in smokeqt and python-qt4 that are new
and appear to be due to the size (-fpic/-fPIC issue)).
The .debdiff is attached, for your convenience to read through and
comment on it already. I’m currently building this, and I’ll report
success (or not) in about a week (since it takes at least five days
for this to compile, from experience).
Changelog:
+ * m68k-ada.diff: Add gcc-4.8.0-m68k-ada-pr48835-2.patch and
+gcc-4.8.0-m68k-ada-pr51483.patch by Mikael Pettersson, to
+fix more CC0-specific and m68k/Ada-specific problems.
Two suggested patches, which I just folded into m68k-ada.diff
for simplicity. Applied on m68k only, as it was previously.
+ * m68k-picflag.diff: New, backport from trunk, by Andreas Schwab,
+to avoid relocation errors when linking big shared objects.
+ * pr58369.diff: New, backport from trunk, by Jeffrey A. Law,
+to fix ICE while building boost 1.54.
The aforementioned two new issues. Always applied: m68k-picflag
doesn’t affect other platforms, and pr58369 is “always applied”
in GCC trunk too, but if you disagree with this, feel free to
apply it m68k only.
+ * pr52306.diff: Supersedes pr52306-retry-hack.diff (in debports
+unreleased), disables -fauto-inc-dec by default on m68k to
+work around ICE when building C++ code (e.g. Qt-related).
As discussed above: changing the default, m68k only.
+ * rules.conf: Do not force libcloog-isl-dev (>= 0.18) on older
+distribution releases that do not have this version yet.
ISTR writing about this already: as I regularily build cross
compilers for wheezy/amd64 which doesn’t have this version
yet, and all other new version dependencies are for sid and
whatever animal *buntu has as development version only (and
the changelog entry adding the 0.18 restriction indicates it
was only done to force the transition in Debian), I disabled
this for “older” releases, just like the mpc version dependency.
