[Buildroot] blktrace fails to build on ARC

[Thomas Petazzoni]

Hello ARC maintainers,

I don't know if you have noticed, but the blktrace package fails to
build on ARC, since quite some time:

  http://autobuild.buildroot.net/?reason=blktrace-1.%

There is a toolchain issue:

/home/test/autobuild/run/instance-2/output/host/opt/ext-toolchain/bin/../lib/gcc/arc-buildroot-linux-uclibc/7.3.1/../../../../arc-buildroot-linux-uclibc/bin/ld: btreplay: hidden symbol `__st_r13_to_r17' in /home/test/autobuild/run/instance-2/output/host/opt/ext-toolchain/bin/../lib/gcc/arc-buildroot-linux-uclibc/7.3.1/libgcc.a(_millicodethunk_st.o) is referenced by DSO
/home/test/autobuild/run/instance-2/output/host/opt/ext-toolchain/bin/../lib/gcc/arc-buildroot-linux-uclibc/7.3.1/../../../../arc-buildroot-linux-uclibc/bin/ld: final link failed: Bad value

Could you have a look ?

Thanks,

Thomas
