commit 89df5d6cce0e91c4b34c7a62ba4a68756a8ed4e7
Author: Pedro Alves <palves@redhat.com>
Date:   Thu Mar 31 19:28:47 2016 +0100

    Make gdb.base/jit.exp binaries unique
    
    This testcase compiles the same program and library differently
    multiple times using the same file names.  Make them unique, to make
    it easier to debug test problems.

    	PR gdb/19858
    	* gdb.base/jit.exp (compile_jit_test): Add intro comment.  Add
    	BINSUFFIX parameter, and handle it.
    	(top level): Adjust calls compile_jit_test.
