[PATCH 2/3] Make gdb.base/jit.exp binaries unique

[Pedro Alves <palves@redhat.com>]

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.

gdb/testsuite/ChangeLog:
2016-03-23  Pedro Alves  <palves@redhat.com>

	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.
