Created attachment 683632 [details] build.log build log and emerge --info
I believe this is no longer a problem, looking at mesa-21.0.0_rc3 we have LLVM in RDEPEND and RDEPEND mapped onto DEPEND, so the LLVM will be present prior to merging mesa, meaning llvm.eclass will no longer throw this error.
