Re: I have submitted bugzilla 221107 for a (e.g.) -r321706 system clang 5 vintage TARGET_ARCH=powerpc buildkernel failure for aha.kld: R_PPC_PLTREL24 reloc against local symbol

[-r322109 update failed for agp.kld instead. It may just be
a race for which happens first during the build.]

I have updated bugzilla 221107 for that building -r322109
