BaseTools GCC: align start of .data to .text alignment
BaseTools GCC: align start of .data to .text alignment

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.
