Likely related to this:

// HACK: LLVM versions 19+ do not have the FPMR feature and treat it as always enabled

Perhaps in the interim you can upgrade and use LLVM 19? Or downgrade to a version of LLVM 18 where "+fpmr" option is accepted?

Triage: minimum external LLVM is now 19 following #139275, +fpmr is not supported because upstream doesn't support it anymore.

Installing dufs in termux will also give the same warning

cargo install dufs
