Add a comment and make them depend on libX11_xcb instead of just libX11.
The libraries which do not actually use the connection but just call APIs
are left alone.
Preparation for BeXlib (which is a ways off, but this will allow me
to build things in HaikuPorts against it properly.)
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.
* Drop unneeded calls to libtoolize and autoreconf.
* Install README in $developDocDir for primary arch builds.
* Drop $manDir on secondary arch builds.
* Sort BUILD_PREREQUIRES.
* Switch HOMEPAGE to https.
* Switch SOURCE_URI to tar.bz2.
