[PATCH] sim: common: delete configure & Makefile

* Mike Frysinger via Gdb-patches <gdb-patches@sourceware.org> [2021-01-17 05:36:31 -0500]:

> This was mostly orphaned a while back, but left behind so people could
> still run `make headers`.  Merge that one target to the top sim dir and
> delete all the build logic.  This should avoid confusing people further.
> 
> sim/:
> 	* Makefile.in (abs_srcdir, srcroot, CPP): Define.
> 	(nltvals): New target.
> 	* README-HACKING: Change headers to nltvals.
> 
> sim/common/:
> 	* configure, configure.ac, Makefile.in: Delete.

LGTM.
