Pedro Alves dc3a371e83 gdb/testsuite: Explicitly return from main
I've been playing with a board file that forces every testcase to
include a header file that does something like:

  #define main __gdb_testcase_main

and then links an actual main() function that does some
initialization and then jumps to __gdb_testcase_main.

That runs into a number of testcases relying on main not having an
explicit return statement, like e.g.,:

 gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.base/catch-follow-exec.c:27:1: warning: non-void function does not return a value [-Wreturn-type]
 gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.base/catch-signal.c:47:1: warning: non-void function does not return a value [-Wreturn-type]

We don't get those warnings without my board because it is valid to
not explicitly return from main.  There's an implicit "return 0;".

Since it doesn't hurt to be explicit, I've went ahead and added the
explicit return statements.

Also, a couple testcases either don't explicitly specify main's return
type, or return void.  Those are tweaked to explicitly return int.

gdb/testsuite/ChangeLog:

	* gdb.base/catch-follow-exec.c (main): Add explicit return
	statement.
