x86_64 is used as a baseline: the "x86_64" entry, whatever status it has,
is transformed into "all", and then the other entries in ARCHITECTURES
either dropped or rearranged appropriately.
This is required because check 0.11.0 no longer builds on x86_gcc2
primary arch, so the arch-independent check_common could not be
built on x86_gcc2, hence preventing the installation of check_x86.
* 0.9.13, 0.9.14 and 0.10.0 were missing a cmd:gawk in REQUIRES.
* Fixed 2nd arch for 0.10.0 and improved the package splitting.
* Switch 0.9.13 and 0.9.14 to the same layout as 0.10.0.
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
* fix dependencies and build system
* check doesn't build correctly with haikuporter on x86_64 beause
of a Python bug (hard link extraction in tar files)
