fixed-point/composite-type: add -Wno-array-parameter

fixed-point/composite-type: add -Wno-array-parameter

[Alexandre Oliva]

On machines that support fixed-point and the test runs, it's failing
because of warnings issued by -Warray-parameter=[12], enabled by
-Wall.

The warnings state "mismatch in bound 1 of argument 1 declared as...",
referring to the redeclaration of f2_##NAME.  The purpose of the
redeclaration is not clear to me.

It doesn't look like the test intends to catch mismatches between
parameter's array lengths, despite the explicit array bound and the
incompatible calls, so I'm adding -Wno-array-parameter to avoid this
distraction and enable the test to pass.

Tested on arm-eabi, where the patch removes the excess errors fail.  Ok
to install?

Sounds reasonable.  OK.
