[PATCH] gas: allow disabling dollar-as-line-separator for AVR target

[Nick Clifton]

Hi Matt,

> 	* config/tc-avr.c (enum options): Add option flag.
> 	(struct option): Add option -mno-dollar-line-separator.
> 	(md_parse_option): Adjust treatment of $ when option is present.
> 	* config/tc-avr.h: Use avr_line_separator_chars.

Approved and applied.

Note - you missed a couple of things:

   * The usage() function in tc-avr.c is used to add AVR specific
     output to the assembler's --help command line option.  So it
     needed to be updated to mention the new option.

   * The gas/doc/c-avr.texi file documents the AVR specific command
     line options, as well as the special characters, so this too
     needed updating.

To save you the trouble however I have taken care of both of these
issues.

Cheers
   Nick
