add s390_gcc_target_options
This adds s390_gcc_target_options, an implementation of the new "gcc_target_options" gdbarch method. This was needed because the default implementation of the method doesn't work properly for S390, as this architecture needs "-m31" rather than "-m32". gdb/ChangeLog 2014-12-12 Jan Kratochvil <jan.kratochvil@redhat.com> * s390-linux-tdep.c (s390_gcc_target_options): New function. (s390_gdbarch_init): Add it to gdbarch.
