[hardware/velodyne-libs] Upgraded to version 0.7.

Changes since 0.6:
- Separated initialization from the addition of a heading sector.
[hardware/velodyne-genom] Upgraded to version 1.4.

Main changes since 1.3:
- Introduced a target tracking functionality, including a poster and optional
  file output.
- Initiated the split of the module's functionalities into different parts, that
  will probably constitute one or more libraries in the future. At least two
  separate libraries are currently envisaged: one for the target-related
  functionalities and other for the reading-related functionalities.
- Introduced a playback mode, which for the moment is quite simplistic.

Secondary changes since 1.3:
- Improved the use of external variables.
- Updated header inclusions.
- Improved error handling.
- Improved formatting.
- Improved naming.
- Improved documentation.

[mk/sysdep] Fix a typo in wxwidget sysdep
[mk/update] Fix a glitch when printing error messages due to package conflicts

Errors messages must be appended to ${_UPDATE_LIST}.err and are printed
altogether once all packages have been scanned.

Should fix a PR by Pierrick Koch on the mailing list. Thanks!
[mk] Do not artificially create empty variables in the 'trusted' environment

Re-export only those variable that where actually defined, otherwise the
trusted environment may artificially create empty variables (which is not
exactly the same as undefined variables).
[mk/plist] Fix a typo in the definition of ignored directories in print-PLIST

The variable must not be assigned with immediate expansion := because the value
may contain recursive definitions.
[mk/plist] Fix DYNAMICS_PLIST_DIRS handling in presence of absolute directories

Strip ${PREFIX} from DYNAMIC_PLIST_DIRS so that either relative or absolute
dirs can be given.
[mk/depends] Fix brace expansion in prefix in prefixsearch.sh

The expansion of "a{x,y} b{x,y}" is not the same as "a{x,y}b{x,y}", because of
IFS. The first should expand to "ax ay bx by", while the second should expand
to "axbx axby aybx ayby".

So make sure to split words at IFS before passing them to the brace expansion
routine.
[mk/depends] Improve prefixsearch error reporting

* Fix error reporting when the custom command extracting a sysdep version
  fails. Not sure why this was not properly checked already.

* Add a fifth optional field in the SYSTEM_SEARCH specification, that is to be
  printed in lieu of the actual sysdep file name. This is intented for obscure
  SYSTEM_SEARCHs, like the one used in mk/sysdep/tex-pkgs.mk
[mk/sysdep] Update error reporting in tex-pkg.mk

Use the new 'comment' field of SYSTEM_SEARCH to properly report what is not
found, if needed.
[mk/extract] Fix the separation between extract-vars.mk and extract.mk

This pursues the long term goal of having *-vars.mk only defining
variables.
[mk/build] Isolate gmake specific settings from the generic build-vars.mk

A new mk/build/gmake.mk file is created. It holds gmake specific settings for
the build phase. No functional change expected.
