Hi!
https://bugzilla.redhat.com/show_bug.cgi?id=910926
reports that plugins aren't usable on arm, because arm-cores.def isn't
installed into the plugins directory. arm-cores.def can't be included in
tm_file list, because we don't want to include it directly, nor in
HeaderInclude in arm.opt (that breaks the build). rs6000 has similar issue
with its rs6000-builtin.def, and solves this by adding content to TM_H
in Makefile fragment.
Thus, the following patch does the same for arm (and apparently aarch64 has
the same issue). Ok for trunk?

* config/aarch64/t-aarch64 (TM_H, OPTIONS_H_EXTRA): Add
aarch64-cores.def.
* config/arm/t-arm (TM_H, OPTIONS_H_EXTRA): Add arm-cores.def.
