devel/freebsd-gcc12 based amd64 buildworld buildkernel: a Failure notice ( non-debug buildworld ) + Messages ( buildkernel 's)

Non-debug buildworld Failure notice :

/usr/local/bin/x86_64-unknown-freebsd14.0-ld: /usr/obj/BUILDs/main-amd64-nodbg-gccxtc/usr/main-src/amd64.amd64/lib/libblacklist/libblacklist.a(bl.o): relocation R_X86_64_32 against `.rodata' can not be used when making a PIE object; recompile with -fPIE
/usr/local/bin/x86_64-unknown-freebsd14.0-ld: failed to set dynamic section sizes: bad value
collect2: error: ld returned 1 exit status

(This prevented the buildkernel that was also listed on the command line. So. . .)

non-debug buildkernel (run separately, by itself) Messagees:
(I show the last of the _dwarf_info_load(229) related messages
and what follows.)

(The later debug buildkernel is similar.)


debug buildworld: completed, no odd messages at the end.

FYI:

# uname -apKU
FreeBSD amd64_ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT main-n260797-dc1b8c9a846e GENERIC-NODBG amd64 amd64 1400079 1400079

It was rebuilding variations of itself, but via devel/freebsd-gcc12 .
