I should also have noted that poudriere leaves
logs around to look at, of the form:

/usr/local/poudriere/data/logs/bulk/JAILNAME/latest-per-pkg/llvm10-10.0.1_5.log

(using llvm10-10.0.1_5 as an example).

With the log you can see the steps that it takes, including
what OPTIONS were in use, extracting from dist files,
installing packages, and so on. Toward the end should be the
errors that stopped the build. The command lines that were
in use are present.

The log shows a list of the targets:

-- Targeting AArch64
-- Targeting AMDGPU
-- Targeting ARM
-- Targeting BPF
-- Targeting Hexagon
-- Targeting Lanai
-- Targeting Mips
-- Targeting MSP430
-- Targeting NVPTX
-- Targeting PowerPC
-- Targeting RISCV
-- Targeting Sparc
-- Targeting SystemZ
-- Targeting WebAssembly
-- Targeting X86
-- Targeting XCore

(The above was from an amd64 context that does build
llvm10 for multiple targets.)
