All,

gcc.target/arm/pr42835.c started failing as a result of the following
change which add tree-tail merging:
   http://gcc.gnu.org/viewcvs?view=revision&revision=179275

The behaviour of the testcase with tree-tail merging is correct, but not 
what is expected.

The attached patch adds -fno-tree-tail-merge to the test options.

Tested arm-none-eabi.

Can someone review and approve please?

Thanks,

Matt
