Building cross toolchain on cygwin from source

I am using a crosstool-NG system. During configuration of GMP it
throws the following error

"could not find a working compiler"

whereas I have gcc4.9.3 installed and working.

I cant attach logs here at work but can paste it inline if you like.

Thanks and Regards,
