test-c-stack2.sh test failing on Linux sparc64

[John Paul Adrian Glaubitz]

Hello!

The test test-c-stack2.sh fails on Debian unstable sparc64:

FAIL: test-c-stack2.sh

The full build log including testsuite can be found in [1].

I don't know how to get a more verbose test output, so any feedback is welcome.

A SPARC machine running Debian sparc64 is part of the GCC compile farm [2], in 
case someone
needs a machine for testing patches.

Thanks,
Adrian
