Alan Modra 49af2f5c83 bfin: allow ".=.+delta"
BFIN has lots of instructions that contain "=", so "sym = expression"
is disabled for that target.  This makes an exception for assignment
to dot, fixing the recent regression of ld-scripts/pr18963.

	* config/tc-bfin.h (TC_EQUAL_IN_INSN): Allow assignment to dot.
