From src/misc/runner.c:

 *    Silly little bodge for getting GNU make to pass long commands
 *    to broken programs like the Microsoft and Watcom linkers. This
 *    tool is built with gcc, and invoked using GNU make. It echoes
 *    the arguments into a temporary file, and then passes that as a 
 *    script to the utility in question.

Basically, under DOS/Windows the command line is limited to 126 chars. GCC 
compiled programs have a way to bypass that, but it only works between 
themselves.

A quick grep suggests it's used with MSVC and watcom.
