ppe42-gcc: Add build fix
When building with GCC 11, which defaults to C++17:
../.././gcc/reload1.c: In function ‘void init_reload()’:
../.././gcc/reload1.c:89:24: error: use of an operand of type ‘bool’ in ‘operator++’ is forbidden in C++17
89 | (this_target_reload->x_spill_indirect_levels)
| ~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
../.././gcc/reload1.c:444:7: note: in expansion of macro ‘spill_indirect_levels’
444 | spill_indirect_levels++;
| ^~~~~~~~~~~~~~~~~~~~~
Make the same fix as was made upstream:
