PATCH: tweak dectest.exp test driver

[Ben Elliston]

I'm committing the following simplification to dectest.exp as obvious.
This test driver is only used when the $DECTEST environment variable
is set anyhow, so will not affect anyone.

        * gcc.misc-tests/dectest.exp (TORTURE_OPTIONS): Include -Os.
        Remove target conditional torture options for i?86 and x86-64
        GNU/Linux.
