The CLANG38 toolchain creates a PIE binary at link time. This is necessary since the LTO code generation may otherwise result in code that cannot execute correctly when loaded above 2 GB. PIE executables contain a RELA section consisting of dynamic relocation entries that are intended for consumption by the loader at runtime. For this reason, it has the SHF_ALLOC attribute set by default, and will be identified by GenFw as a section that needs to be copied into the PE/COFF binary, resulting in waste of space since the PE/COFF loader does not use this data at all. So mark the RELA section as informational: this will prevent the linker from setting the SHF_ALLOC attribute, causing GenFw to ignore it.
