It broke when ld.lld became the default powerpc linker. USE_LLD = No
is the same workaround as in gcc 8. Add a comment to both 8 and 11,
# powerpc lld can't link C++ code from gcc, "ld: error: relocation
# refers to a discarded section:" .data.rel.ro.* or
# .sdata.DW.ref.__gxx_personality_v0
USE_LLD = No
ok pascal@ (maintainer)
