I do not fully grasp this yet and suspect and x-y-problem on my side. So
let me step back a little and explain where I am coming from to see
where we should be going:
When building a stage1 cross compiler for hppa (DEB_TARGET_ARCH=hppa
DEB_CROSS_NO_BIARCH=yes DEB_STAGE=stage1), I got a configure error that
no hppa64-linux-gnu-ld could be found. I (wrongly) concluded that this
would be a multilib issue and indeed setting gcc's internal with_hppa64
variable to disabled would make the stage1 (uselessly?) succeed. The
binutils I used were built with WITH_SYSROOT=/ TARGET=hppa. So there are
basically two options to solve this bug:
* binutils learns to produce hppa64-linux-gnu-ld
* gcc learns not to use hppa64-linux-gnu-ld
In the light of your answer the latter seems unlikely. Is it correct
that the binutils cross build should produce a hppa64 ld?
Looking again at the binutils debian source, I can see that see a number
of branches on hppa that add hppa64 functionality, but they branch on
DEB_HOST_ARCH. It seems that the current binutils package only supports
reverse cross builds for hppa64 and no forward cross builds. Is this
correct?
