[Patch, testsuite] missing -ftrack-macro-expansion=0 option in gcc.dg/builtin-stringop-chk-1.c

[Greta Yorsh]

The test gcc.dg/builtin-stringop-chk-1.c fails on arm-none-eabi because the
command line option -ftrack-macro-expansion=0 is missing. 

This command-line option has recently been added to dg-options directive in
this test, but for arm targets the first dg-options directive in the test is
overwritten by a second dg-options that does not contain
-ftrack-macro-expansion=0.

This patch replaces the second dg-options directive with
dg-additional-options. Fixed test passes on qemu. 

OK for trunk?

Thanks,
Greta

        * gcc.dg/builtin-stringop-chk-1.c (dg-options): Replace
        dg-options for target arm with dg-additional-options.
