They all failed initially like this:

/vol/gcc/src/hg/trunk/local/gcc/dwarf2out.c:3205:21: error: poisoning existing
macro "DWARF2_ASM_LINE_DEBUG_INFO" [-Werror]
  #pragma GCC poison DWARF2_ASM_LINE_DEBUG_INFO
                     ^~~~~~~~~~~~~~~~~~~~~~~~~~
/vol/gcc/src/hg/trunk/local/gcc/dwarf2out.c:3217:21: error: poisoning existing
macro "DWARF2_ASM_VIEW_DEBUG_INFO" [-Werror]
  #pragma GCC poison DWARF2_ASM_VIEW_DEBUG_INFO
                     ^~~~~~~~~~~~~~~~~~~~~~~~~~

Removing the #pragma GCC poison and trying again...
