[PATCH 8/8] Tests for validate symbol file using build-id.

[Aleksandar Ristovski <ARistovski@qnx.com>]

Notable changes: Changed regexp to expect Yes/No and ${solibfile} on a 
single line only.

	* gdb.base/solib-mismatch-lib.c: New file.
	* gdb.base/solib-mismatch-libmod.c: New file.
	* gdb.base/solib-mismatch.c: New file.
	* gdb.base/solib-mismatch.exp: New file.
