    testsuite: Fix g++.dg/warn/Wstringop-overflow-6.C on Solaris [PR123135]

    The g++.dg/warn/Wstringop-overflow-6.C test FAILs on Solaris:

    FAIL: g++.dg/warn/Wstringop-overflow-6.C  -std=gnu++11 (test for excess
errors)

    with

    Excess errors:
    /usr/include/iso/math_c99.h:361: warning: ignoring '#pragma
does_not_read_global_data ' [-Wunknown-pragmas]

    and

    /usr/include/errno.h:93: warning: ignoring '#pragma no_side_effect '
[-Wunknown-pragmas]

    Those pragmas are specific to the Studio compilers but unrelated to the
    testcase, so this patch disables the warnings on Solaris.

    Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and
    x86_64-pc-linux-gnu.
