I managed to not have poudriere using base/binutils but instead:
# /usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils-poud/usr/bin/ld -v
GNU ld 2.17.50 [FreeBSD] 2007-07-03
cc and c++ were as they should have been:
# /usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils-poud/usr/bin/cc -v
FreeBSD clang version 8.0.0 (tags/RELEASE_800/final 356365) (based on LLVM
8.0.0)
Target: powerpc64-unknown-freebsd13.0
Thread model: posix
InstalledDir:
/usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils-poud/usr/bin
# /usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils-poud/usr/bin/c++ -v
FreeBSD clang version 8.0.0 (tags/RELEASE_800/final 356365) (based on LLVM
8.0.0)
Target: powerpc64-unknown-freebsd13.0
Thread model: posix
InstalledDir:
/usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils-poud/usr/bin
So I was not testing the tools combination that I thought/intended.
