[Gm2] Previous problem with build on Raspberry Pi has returned

[JD]

Gaius,
After my long run, reaching the point where you thought "it was running the compiler to find out the builtin types and functions", I didn't do any debugging as I noticed that my filesystem was corrupt and almost full.

I've re-installed Raspbian, then installed libmpfr-dev libgmp-dev libmpc-dev flex & dejagnu.  I couldn't find a gcc-multilib - this could be my problem.

I copied the directories asm, bits, gnu & sys to /usr/include.
I linked the 3 'crt' files to ~/GM2/scratch-area/build-4.7.3/./gcc/ as before.
On the next run I realised something ridiculous about my previous attempts.  After linking the crt files I was at first just re-running make.  You advised me to re-run configure as well, so I started at the top again.  This meant that everything below GM2 was deleted, including the linked crt files.  But even so it ran and ran - for 7 days!  Why?

Now, though, my RPi has become a lot more sensible and it consistently fails if the crt files are not where expected.  I now ensure they are available by putting in commands to create the gcc directory immediately after the configure and then linking the files.

The failure I cannot overcome is the same or similar as one I reported before the re-install (see  V90 issue 4):

usr/bin/ld: error: ./libgcc_s.so.1.tmp uses VFP register arguments, pr-support_s.o does not
/usr/bin/ld: failed to merge target specific data of file pr-support_s.o

make[1]: Leaving directory `/home/jd/GM2/scratch-area/build-4.7.3'
make: *** [all] Error 2

On my original runs this failure also disappeared after a while and the build ran almost to the end as you know.  The only change I thought might have an effect now is in the configure options:  I changed disable-multilib to enable-multilib and added enable-multiarch .  No difference.

Any ideas?

John
