stage4 bootstrap exits with error 2 on 32-bit Debian arm-linux-gnueabi

[Dennis Clarke <dclarke@blastwave.org>]

Thanks to help from Jonathan Wakely and Xi Ruoyao the little 32-bit arm
board from ASUS finally did get somewhere past stage1 in the bootstrap.

However after many hours of slowly smashing away at the silly SDIMM in
the ASUS STinkerBoard we get all the way to stage4 ( maybe? ) :


io$ /usr/bin/time -p /usr/bin/nice -n +18 make -j 2 bootstrap4

Yes, this really did take 15 hours and 39 minutes to get to this point.

io$ cat stage_current
stage4
io$

If anyone wonders why the bootstrap4 then the only answer I have is "why 
not?" given what I see at : https://gcc.gnu.org/install/build.html

     make BOOT_CFLAGS='-O' bootstrap

     You can place non-default optimization flags into BOOT_CFLAGS; they
     are less well tested here than the default of ‘-g -O2’, but should
     still work. In a few cases, you may find that you need to specify
     special flags such as -msoft-float here to complete the bootstrap;
     or, if the native compiler miscompiles the stage1 compiler, you may
     need to work around this, by choosing BOOT_CFLAGS to avoid the parts
     of the stage1 compiler that were miscompiled, or by using ‘make
     bootstrap4’ to increase the number of stages of bootstrap.


Well, after some messing around I did need to use --enable-multiarch and
the mysterious --with-float=hard in configure. I wonder if I can get
away with just using those for stage1 ? That is a whole other question
but for now I am curious what the error could be all the way into stage4
as seen above?  Any thoughts?
