A look into the current gas sources finds this in config/tc-ppc.h:
/* $ is used to refer to the current location. */
#define DOLLAR_DOT
so apparently this is indeed standard behavior for gas on PPC. There's
no indication that you could turn it off without manually hacking this
config header.
Source code access to one's tools is so pleasant ...
