Comment (by Ben Gamari <ben@…>):

 In [changeset:"5f5d0c9d43bbab922582f437c4a1a3f06ff3fd0e/ghc"

 revision="5f5d0c9d43bbab922582f437c4a1a3f06ff3fd0e"
 Mark test broken on powerpc64[le]

 Test num009 fails different results. #15062 lists more issues on other
 platforms. Test T14894 fails because DWARF support is not implemented in
 the PowerPC native code backend. T5435_v_asm_b fails because the runtime
 linker is not implemented for PowerPC 64-bit systems.

 Test Plan: validate
