Now the test toolchain partially works, the same way as
with the previously modded LiberoSoC tool.

The reason is that there is an incompatibility between
LiberoSoC version prior and after v12.

This allows for Makefile .mk includes that can access and use
the top level Makefile variables defined/generated by HDLMake,
like TOP_MODULE, detected TOOL_PATH, etc.

This feature can be used for e.g. adding make targets/recipes
to genete or convert flash ROM files.

Add support to NVC simulator

See merge request !27

So that architecture or package bodies in a separate file
don't create circular dependencies

Fails due to architecture is compiled before entity

Further make -n shows a circular dependency (similar as in testcase 125):
make: Circular work/hdlmake/gate4_x_a_vhdl <- work/hdlmake/gate4_e_vhdl dependency dropped.

After running pytest not everything was cleaned up, it is now.

The stuff that wasn't cleaned up was:
- Some Makefile's
- 020git_fetch/ipcores.old/
- 048err_two_manifest/manifest.py

If a package body exists, then it is included as dependency for its package.

Note:
This implementation does not handle selecting the correct architecture
between multiple architectures.

All testcases pass

If entity and architecture are in separate files, then the
architecture isn't included in dependencies.

Vivado: Compile to --work <library>

Prior Vivado compiled to work, now it compiles to the library specified in Manifest.py

Add partial support for VHDL generic packages

See merge request !21

This adds support for generic packages declaration dependency
tracking. It is not complete though, it only works when instantiating
a generic package for using withing the same file.

so hdlmake can satisfy dependencies declared by qips
