gdb/printcmd.c: Fix printing of Thumb minimal symbols.

In build_address_symbolic we call gdbarch_addr_bits_remove for
symbols in the symbol table but not for minimal symbols. This
causes a failure in gdb.cp/virtfunc.exp on ARM, as the address
of the virtual thunk is given an offset of 1 when in Thumb mode.

	* printcmd.c (build_address_symbolic): Call
	gdbarch_addr_bits_remove for text minimal symbols.
