760b3e8bc9 sim: common: split up acinclude.m4 into individual m4 files 
This file is quite large and is getting unmanageable.  Split it apart
to follow aclocal best practices by putting one-macro-per-file.  There
shouldn't be any real functional changes here as can be seen in the
configure script regens.

136da8cd9c sim: switch to AC_CONFIG_MACRO_DIRS 
Rather than hand maintain m4 includes in various autotool files,
use AC_CONFIG_MACRO_DIRS to declare the relevant search paths.
This simplifies the code, makes it more robust, and cleans out
unused logic from configure.
