$XDG_DATA_HOME (~/config/non-packaged/data) should always be there,
so avoid errors while tryiing to mkdir() it again while trying to
create the "calcurse" subdir.
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.
* Create recipe for calcurse
A few things of note:
* The default terminal font, Noto Mono, does not support the box
drawing characters that calcurse relies on. Changing the font to Noto
Sans Mono fixes this issue.
* calcurse's default date format (format.dayheading) uses the %-d
format sequence, which Haiku's version of `date' does not support.
This can easily be fixed by changing it to %d in calcurse's config.
* The checks for lm and pthread are patched out in configure.ac, as
these libraries are contained within libroot in Haiku.
