The deletion of the #undefinition of SKIP_TRAMPOLINE_CODE isn't
mentioned in the ChangeLog entries; was it intentional?  If I'm
following the code right, the effect is to change the method from
using generic_skip_trampoline_code (the gdbarch default) to using
find_solib_trampoline_target (#defined in config/tm-sysv4.h, #included
from config/tm-linux.h, #included from config/s390/tm-linux.h), so it
seems like something that deserves mention.
