This flag is defined inside of libpri.h, which is included by 
chan_dahdi.c, which is why you do not see it inside chan_dahdi.c.

2BCT will automatically compile by default if the version of libpri you 
have support 2BCT.  If you have any version of libpri newer than a year 
or two ago, it supports all the currently supported switchtypes.  In 
fact, the earliest version of 2BCT supported was done probably 3 or 4 
years ago (RLT for DMS switches), so even very old versions of libpri 
will support compilation of that code.
