Hi Thomas,

Sparc v8 sees some build errors:

http://autobuild.buildroot.net/results/de7/
de7079b89fda1dd47e52619a644f23c4f4986b2c//

ERROR: architecture for "/usr/lib/libmpeg2convert.so.0.0.0" is "Sparc v8
+", should be "Sparc"

Patching arch/Config.in.sparc like this

@@ -30,5 +30,6 @@ config BR2_GCC_TARGET_CPU
        default "ultrasparc"    if BR2_sparc_v9
 
 config BR2_READELF_ARCH_NAME
+       default "Sparc v8+"     if BR2_sparc_v8
        default "Sparc"         if BR2_sparc
        default "Sparc v9"      if BR2_sparc64

does not fix the problem however:

target...
