[Buildroot] [PATCH] autobuild-run: do not build evtest using extrenal arc-2014.12 toolchain

[Alexey Brodkin]

This external arc-2014.12 toolchain has uClibc with disabled
UCLIBC_HAS_PROGRAM_INVOCATION_NAME.

Because of this following build failure happens in autobuilder -
http://autobuild.buildroot.net/results/0fd/0fd36a0d79c4d82aedebb5aca8d3ce4214b1ed61/
--->8---
evtest.c: In function 'version':
evtest.c:730:20: error: 'program_invocation_short_name' undeclared (first use in this function)
  printf("%s %s\n", program_invocation_short_name, PACKAGE_VERSION);
                    ^
evtest.c:730:20: note: each undeclared identifier is reported only once for each function it appears in
evtest.c: In function 'usage':
evtest.c:742:38: error: 'program_invocation_short_name' undeclared (first use in this function)
  printf("   %s /dev/input/eventX\n", program_invocation_short_name);

Mentioned config option was recently enabled in uClibc's defconfig for ARC:
https://github.com/foss-for-synopsys-dwc-arc-processors/uClibc/commit/c2460b9b7b8c76098dfb1313be4aa4a4a65ff619

So newer ARC uClibc toolchains should build evtest perfectly well.

I've marked this patch as Rejected, since I have committed another
patch to mark the Synopsys ARC external toolchain as "broken" because
the uClibc configuration is too far from the default Buildroot uClibc
configuration. We'll re-enable this toolchain once a new release is
made upstream, as we discussed.

Thanks,

Thomas
