List of packages that fail to build under clang, but fine with GCC

• GRUB
• libedit
• efibootmgr (cannot find efivar.h)
• graphite (expects libgcc_s.so)
• Bluez
• pcre (not pcre2. Configure script cannot find libbz2)

List of packages that fail to build under clang AND gcc. Likely requires a system with GCC as primary toolchain

• rust fails to build with clang. Errors with unresolved symbols from libLLVM.so. If build using gcc, build still fails as build tries to compile with -stdlib=c++... perhaps need to modify build to build rust ENTIRELY with a bootstrap rust toolchain. Thanks to patches from Chimera Linux, rust compiler can be compiled by clang.
