Re: [config]: patch fix program-transform-name

[Khem Raj <khem at mvista dot com>]

Hi

I found problems when building canadian cross compiler with the patch I 
sent when the program-transform-name was set to empty. I reworked the 
patch now it sets ncn_target_tool_prefix to program-transform-name first 
and then checks if it is empty then does the esxisting check.

Tested on arm-linux-gnuabi, powerpc-unknown-linux
i686-montavista-linux and  mips-unknown-linux

Is this OK?

Thanks

     * acx.m4: Use program_transform_name to compute 
ncn_target_tool_prefix.
