    [gdb/testsuite] Fix gdb.ada/verylong.exp on 32-bit target

    In an aarch32-linux chroot on an aarch64-linux system, I run into:
    ...
    (gdb) print x^M
    $1 =3D 9223372036854775807^M
    (gdb) FAIL: gdb.ada/verylong.exp: print x
    ...

    A passing version on aarch64-linux looks like:
    ...
    (gdb) print x^M
    $1 =3D 170141183460469231731687303715884105727^M
    (gdb) PASS: gdb.ada/verylong.exp: print x
    ...

    The difference is caused by the size of the type Long_Long_Long_Integer,
which
    is:
    - a 128-bit signed on 64-bit targets, and
    - a 64-bit signed on 32-bit target.

    Fix this by detecting the size of the Long_Long_Long_Integer type, and
    handling it.

    Tested on aarch64-linux and aarch32-linux.
