Hi,

	This fixes up documentation for the -marm option and changes the 
behaviour of mthumb to reject the negative options to bring this to 
behave similar to the marm option. The option needs to be documented 
since we now have situations where toolchains default to Thumb state and 
folks need a way of overriding this. I would like a review of this 
before committing it since this is a change to the command line options.

Tested by building a cross toolchain to arm-linux-gnueabi and verified 
that -mno-thumb is rejected and looking up the documentation after it 
was rebuilt.

Ok ?

cheers
Ramana
