Ard Biesheuvel 56948ba190 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.

Ard Biesheuvel efe690cab3 BaseTools GCC: add unified GCC linker script for all archs and versions
This unifies all GCC linker scripts into a single parametrised GCC
linker script that can be used for all GCC versions and architectures.

The two parameters that can be set on the linker command line are:
- PECOFF_HEADER_SIZE, this is a build time property of GenFw, but
  its value is different between 32-bit and 64-bit;
- common-page-size, this can be set using -z on the ld command line,
  and controls the value of the COMMONPAGESIZE constant when used in
  a linker script. This value is used for the minimum section alignment.
