I googled around and found: https://github.com/anholt/libepoxy/pull/158. dlvsym seems to be a glibcism. Note that upstream support BSDs and all sorts of platforms, so this shouldn't be a problem. I found this: https://reviews.llvm.org/D63785. It looks like we need DCOMPILER_RT_BUILD_WITH_MUSL=$(usex elibc_musl) in the ebuild.
This has been fixed in LLVM 12: https://reviews.llvm.org/D93848
