Many thanks Mathieu,
This looks good to me. I'm about to
Control: tags -1 patch
Here is a patch which solve the symptoms. The underlying bug is within
gcc internals where atomics operations are not implementation for
ppc32 targets.
Description: Make the test suite compile on ppc32
where atomics implementation are missing
The code simply check ppc32 vs
As reported upstream ppc32 does not support those atomic operation
natively and the software implementation is not present either (as of
4.9.1).
Since the implementation is only needed to run a particular test of
the test suite, it should be ok to simply remove compilation of this
test.

I have reduced the issue to the following. Simply compile it from a
Debian/PowerPC based computer:
$ cat t.c
#include
int main()
{
int64_t x = 0, y = 1;
y = __sync_val_compare_and_swap(&x, x, y);
return 0;
}
$ gcc t.c
/tmp/ccAS9Llh.o: In function `main':
t.c:(.text+0x64): undefined refere
Seems like it was fixed already:
