[RFA] gdb.base/mips_pro.exp

[Michael Elizabeth Chastain]

Here is take #2 on my small patch to gdb/testsuite/gdb.base/mips_pro.exp .
Thanks to some feedback from Fernando Nasser, it's even smaller now
(it continues using gdb_test instead of gdb_expect).

(1) Add a comment with the warning messages from the original PR 3016,
    which was filed in 1993.  If we ever see these messages again,
    I think having these comments will help.

(2) Remove setup_xfail for the hppa case.  I have results from running
    this test case on hppa1.1-hp-hpux10.20 which indicates that this
    test is fine for this platform.

(3) The important part: changes the test case to accept a stack trace
    of "middle -> main" as well as "middle -> top -> main".  This fixes
    the test failure.
