[ARM PATCH] Tweak arm_init_tls_builtins for gfortran

["Roger Sayle" <roger at eyesopen dot com>]

gfortran on the ARM?  The following patch tweaks the ARM backend the same
way as I recently fixed the alpha backend, to avoid warnings from the non
C/C++ front-ends when declaring back-end specific builtins/intrinsics c.f.
http://gcc.gnu.org/ml/gcc-patches/2007-02/msg00325.html

The following patch has been tested on a uberbaum cross compiler to
mips-elf, all default languages, and regression tested with a "make
check-gcc RUNTESTFLAGS=--target_board=arm-sim".  Alas the results (for me)
we pretty horrific, but I could confirm that the relevant gfortran
front-end warnings disappeared (though the tests failed for other
reasons).

Ok for mainline?

        * config/arm/arm.c (arm_init_tls_builtins): Avoid using front-end
        attributes and instead set TREE_READONLY and TREE_NOTHROW directly.
