[edk2-devel] [PATCH 2/5] BaseTools: Generate multiple rules when multiple output files

From: Pierre Gondois <pierre.gondois at arm.com>
This patch modifies the Makefile generation not to stop
adding Makfile rules when the first final target is found.
E.g.:
If the following rules are described in build_rule.txt:
-[Rule1]: .X files generate .Y and .Z files;
-[Rule2]: .Z files generate .Z1 files.
Currently, if a File1.X file was part of the sources of a
module, only [Rule1] would be generated in the Makefile.
Indeed, there are no rules to apply to .Y files: .Y files
are a final target. However, there is still [Rule2] to
apply to .Z files.
This patch also adds a dependency between the first
ouput file of a rule and the other output files.
For instance, with the same example as above, File1.Y
and File1.Z are generated by the following rule:
File1.Y: File1.X
<Generate File1.Y>
<Generate File1.Z>
and the new dependency is:
File1.Z: File1.Y
This is necessary to keep a dependency order during the
execution of the Makefile. Indeed, .Y and .Z files are
generated by the execution of a common set of commands,
and without this rule, there is no explicit dependency
relation between them.

Notes:
v1:
- Generate multiple rules when multiple output files
are specified in the build_rule.txt file. [Pierre]
v2:
- Use the "FileType" variable in the _ApplyBuildRule
function as it is in the current state. [Pierre]
v3:
- Adding Suggested-by [Pierre]
v4:
- No modification. Re-sending the patch with base64
encoding to conserve the right line endings. [Bob]
v5:
- No modification. [Pierre]
