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".
2014-05-16 Jan Kratochvil <jan.kratochvil@redhat.com>
* s390-linux-tdep.c (s390_gcc_target_options): New function.
(s390_gdbarch_init): Add it to gdbarch.
