    [gdb/testsuite] Fix gdb.reverse/i387-env-reverse.exp for -pie
   =20
    When running test-case gdb.reverse/i387-env-reverse.exp for x86_64-linu=
x with
    target board unix/-m32/-fPIE/-pie, we run into:
    ...
    (gdb) PASS: gdb.reverse/i387-env-reverse.exp: push st0
    info register eax^M
    eax            0x56550000          1448411136^M
    (gdb) FAIL: gdb.reverse/i387-env-reverse.exp: verify eax =3D=3D 0x80400=
00
    ...
   =20
    The problem is that the tested instruction (fstsw) only sets $ax, not $=
eax.
   =20
    Fix this by verifying $ax instead of $eax.
   =20
    Tested on x86_64-linux with target boards unix/-m32 and unix/-m32/-fPIE=
/-pie.
