Hi Maxim,

We like XML approach to describe register files. It matches
Xtensa, which requires register files to be easily configurable.
But, we need more time to update Xtensa FSF GDB/GDBSERVER
to start fully using this feature. So this version of Xtensa
FSF GDB/GDBSERVER does not use this new approach.
there is a problem in your patch that breaks GDB's build if you build with enable-targets=all.

xtensa-linux-nat.o is part of ALL_TARGET_OBS which are built when using enable-targets=all. If you now build GDB for example on x86 you have two native files (the one from x86 and always xtensa-linux-nat).

This patch fixes that. Ok to commit?

ChangeLog:

* Makefile.in (ALL_TARGET_OBS): Remove dependency to xtensa-linux-nat.o.
