elf: Support STB_LOCAL dynamic symbols

local symbols can be resolved statically, they don't have to be done dynamically, so this is a slight speedup at load time for produced executables and shared libs. The musl libc also rejects any STB_LOCAL symbols for dynamic symbol resolution, so there it also fixes use of shared libs created by tcc.
