HPPA64 cross binutils build handling

[Sedat Dilek]

[ Need more coffee - last attempt of sending this ]

Happy new 2017 and Hi,

I tried backporting binutils (2.26.1-1ubuntu1~16.04.3) to Ubuntu/precise.

I am aware this is not an ideal platform for such backports and my
good-old-Debian-packaging-days need a refresh.
MIPS64 is BROKEN for GNU/gold in binutils v2.26.1, etc.
But anyway...

I played a bit with 'nocross' and 'nomult' DEB_BUILD_OPTIONS.
My goal is a host-only binutils for AMD64 arch.

While playing, I see that the HPPA64 cross binutils build handling is
done in a separate (unusual) way.
A binutils-hppa64-linux-gnu package is always built
undesiredly/unwantedly even...

$ LC_ALL=C DEB_BUILD_OPTIONS="parallel=3,nocross,nomult" debuild -d

...is set explicitly for building.

So, my suggestion is...

-ifneq (,$(filter $(DEB_HOST_ARCH),amd64 i386 x32 hppa))
-  with_hppa64 = yes
+# XXX: Fix HPPA64 cross binutils build handling when 'with_cross' is set.
+with_hppa64 =
+ifeq ($(with_cross),yes)
+  ifneq (,$(filter $(DEB_HOST_ARCH),amd64 i386 x32 hppa))
+    with_hppa64 = yes
+  endif
 endif
...
 ifneq (,$(findstring nomult,$(DEB_BUILD_OPTIONS)))
   with_multiarch = disabled in DEB_BUILD_OPTIONS
 endif
+# XXX: Fix HPPA64 cross binutils build handling when 'nocross' is set
in DEB_BUILD_OPTIONS.
 ifneq (,$(findstring nocross,$(DEB_BUILD_OPTIONS)))
   with_cross = disabled in DEB_BUILD_OPTIONS
+  with_hppa64 = disabled in DEB_BUILD_OPTIONS
 endif

...to fix this.

Ideas?

My current debdiff is attached.

Thanks.
