Hi Jan,
this new test fails on i686 buildbot slaves,

(gdb) core-file 
/home/gdb-buildbot-2/fedora-x86-64-2/fedora-i686/build/gdb/testsuite/gdb.arch/i386-biarch-core.core
"/home/gdb-buildbot-2/fedora-x86-64-2/fedora-i686/build/gdb/testsuite/gdb.arch/i386-biarch-core.core" 
is not a core dump: File format not recognized
(gdb) FAIL: gdb.arch/i386-biarch-core.exp: core-file

See more in https://sourceware.org/ml/gdb-testers/2015-q1/msg02825.html

I can reproduce these fails on i686-pc-linux-gnu GDB on my
x864_64-linux.  Could you take a look?
