Until someone fixes these limitations in the solib code, adding the
include to the tm*-.h file (and dropping back to multi-arch partial) is
the accepted way of addressing this problem.
Well, so can you then aprove the patch attached? Also please try to
compile gdb with --target=x86_64-unknown-linux and tell me if I can
remove the "broken" flag from MAINTAINERS if you were successfull.

* config/i386/tm-x86_64linux.h: New.
* config/i386/x86-64linux.mt: Add GDB_MULTI_ARCH and TM_FILE
definitions.
Thanks in advance
