Which links to:
  https://openpower.xyz/job/snowpatch/job/snowpatch-linux-sparse/15895//artifact/linux/report.txt

The actual build log of which is:
  https://openpower.xyz/job/snowpatch/job/snowpatch-linux-sparse/15895/artifact/linux/build_new.log

Which contains:
  scripts/Makefile.build:267: recipe for target 'arch/powerpc/kernel/ptrace/ptrace-altivec.o' failed
  make[3]: *** [arch/powerpc/kernel/ptrace/ptrace-altivec.o] Error 1
  make[3]: *** Waiting for unfinished jobs....
  scripts/Makefile.build:505: recipe for target 'arch/powerpc/kernel/ptrace' failed
  make[2]: *** [arch/powerpc/kernel/ptrace] Error 2
  make[2]: *** Waiting for unfinished jobs....
  scripts/Makefile.build:505: recipe for target 'arch/powerpc/kernel' failed
  make[1]: *** [arch/powerpc/kernel] Error 2
  make[1]: *** Waiting for unfinished jobs....
  Makefile:1681: recipe for target 'arch/powerpc' failed
  make: *** [arch/powerpc] Error 2
  make: *** Waiting for unfinished jobs....

Same for ppc64le:
  https://openpower.xyz/job/snowpatch/job/snowpatch-linux-sparse/15896/artifact/linux/build_new.log


So it seems like snowpatch always reports the build as succeeded even
when it fails.
