I don't know if Proj.4 provides axis order information directly. However
this information is provided in the GeoAPI wrappers for Proj.4. Since
those wrappers are in public domain, they could be copied in any project
under any license of your choice. The file is there:
For example the line "ne:" lists the EPSG codes of all geographic CRS
using the "North, East" axis order. The line "sw,ne" lists the EPSG
codes of all projected CRS using the "South,West" axis order and based
on a geographic CRS using the "North,East" axis order.
Note that this directory provides also other information that may be
useful, like a mapping from Proj.4 projection names to EPSG and OGC
