%llc_dwarf just replaces win32 with mingw32 in the OS part of the triple,

lit.cfg
164:llc_dwarf = 'llc'
166:  llc_dwarf += ' -mtriple='+config.target_triple.replace('-win32', '-mingw32')
167:config.substitutions.append( ('%llc_dwarf', llc_dwarf) )

COFF files still get generated with mingw32 as the target anyway, so the relocation will still fail to be computed and the test will hence fail.

But %llc_dwarf isn't used in architecture specific directories like X86/, instead plain llc is used, not sure why.

Thanks,
Charlie.
