Is there a way to disable the generation of dependencies when compiling?
This could cut down compile time.

No. But, if you're not already using the -j option, you can often
significantly reduce build times using make's parallel build option.

ok. Thanks this could be useful for our builds on windows (We are using
LSF to reduce build time when working on linux).

Could you let me know how to pass this option to the XDCtools?

The xdc command accepts the same options that GNU make does;
http://rtsc.eclipse.org/docs-tip/Command_-_xdc#Options GNU make
accepts both -j and --jobs options, so

xdc -j 4
or
xdc --jobs=4

will run 4 jobs concurrently.
