Is that normal for this configuration?!
The new testcase fails for the same reason as the 4000 other tests:
/home/tcwg-buildslave/workspace/tcwg_gnu_0/abe/builds/destdir/x86_64-pc-linux-gnu/arm-eabi/bin/ld:
(__deregister_frame_info): Unknown destination type (ARM/Thumb) in
/home/tcwg-buildslave/workspace/tcwg_gnu_0/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-stage2/./gcc/crtbegin.o
crtstuff.c:(.text+0x5e): dangerous relocation: unsupported relocation
So I don't think this is a problem in the commit, I think it's just a
configuration that isn't well supported.
