Ard Biesheuvel 6f8ecc41d7 BaseTools ARM AARCH64: pass CC flags to linker for XIP modules as well
Commit 478f50990a ("BaseTools GCC: add the compiler flags to the linker
command line") added the compiler flags to the linker command line,
which is required for LTO to function correctly, since it involves code
generation at link time.

This patch failed to update the build rules for XIP modules on AARCH64,
which not only requires the ordinary CC flags but also the XIP CC flags
to prevent the LTO backend to, e.g., emit code that does not adhere to
the strict alignment rules we impose for code that may execute with the
MMU off.

So update the XIP link rules as well. Since AARCH64 and ARM are not
supported by any toolchains in the GCCLD build rule family, drop the
reference to GCCLD while we're at it.

This directory contains the next generation of EDK II build tools and template files.
Templates are located in the Conf directory, while the tools executables for
Microsoft Windows 32-bit Operating Systems are located in the Bin\Win32 directory, other 
directory contatins tools source.

1. Build step to generate the binary tools.

=== Windows/Visual Studio Notes ===

To build the BaseTools, you should run the standard vsvars32.bat script
from your preferred Visual Studio installation or you can run get_vsvars.bat
to use latest automatically detected version.

In addition to this, you should set the following environment variables:

 * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree
 * BASE_TOOLS_PATH - The directory where the BaseTools source is located.
   (It is the same directory where this README.txt is located.)
 * PYTHON_FREEZER_PATH - Path to where the python freezer tool is installed

After this, you can run the toolsetup.bat file, which is in the same
directory as this file.  It should setup the remainder of the environment,
and build the tools if necessary.

Please also refer to the 'BuildNotes.txt' file for more information on
building under Windows.

=== Unix-like operating systems ===

To build on Unix-like operating systems, you only need to type 'make' in
the base directory of the project.

=== Ubuntu Notes ===

On Ubuntu, the following command should install all the necessary build
packages to build all the C BaseTools:

  sudo apt-get install build-essential uuid-dev

=== Python sqlite3 module ===
On Windows, the cx_freeze will not copy the sqlite3.dll to the frozen 
binary directory (the same directory as build.exe and GenFds.exe). 
Please copy it manually from <PythonHome>\DLLs.

The Python distributed with most recent Linux will have sqlite3 module
built in. If not, please install sqlit3 package separately.
