PR6503: verify build-ids of dynamically arriving modules
With the horrible module_sect_attr* hack, the .note.gnu.build-id data
may now be verified.
* runtime/sym.c (_stp_kmodule_check): New function.
* runtime/transport/symbols.c (_stp_module_notifier): Upon MODULE_STATE_COMING,
verify build-ids. Reject the module from further consideration upon a
mismatch.

PR6503: get at dynamic module section addresses via horrible hack (tm)
Since <linux/module.h> does not declare structs module_sect_attr[s],
let's declare it ourselves. We need to get at these, because
otherwise there is no way to get at the build-id section address.
* runtime/autoconf-module-sect-attrs.c: New (partial) autoconf file.
* buildrun.cxx (compile_pass): Build it.
* runtime/transport/symbols.c (_stp_module_notifier): Use our own
modern (2.6.19+) declaration of these structs to pass all section
names/addresses to _stp_kmodule_update_address.

PR6503: note special build-id relocation with -DDEBUG_SYMBOLS
* runtime/sym.c (_stp_kmodule_update_address): Specially
note .note.gnu.build-id pseudo-section being relocated.
