Now that GenFw honors the ELF section alignment when placing the PE/COFF sections in the output, the start of the PE/COFF version of .data will be aligned to the alignment of .text if its alignment is higher than the default. So duplicate this behavior in the ELF output, this will make the memory layout of the PE/COFF binary match the layout of the ELF version more closely.
