sim: generate build dependencies on the fly
Lift the code that GDB is using to generate dependencies on the fly and port it over to the sim. Now people shouldn't have to manually maintain these in their Makefile's. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

# ZW_PROG_COMPILER_DEPENDENCIES
|
||||
# -----------------------------
|
||||
# Variant of _AM_DEPENDENCIES which just does the dependency probe and
|
||||
# sets fooDEPMODE accordingly. Cache-variable compatible with
|
||||
# original; not side-effect compatible. As the users of this macro
|
||||
# may require accurate dependencies for correct builds, it does *not*
|
||||
# honor --disable-dependency-checking, and failure to detect a usable
|
||||
# method is an error. depcomp is assumed to be located in
|
||||
# $ac_aux_dir.
|
||||
#
|
||||
# FIXME: Should use the Autoconf 2.5x language-selection mechanism.

# AM_SET_DEPDIR
|
||||
# -------------
|
||||
# Choose a directory name for dependency files.
|
||||
|
||||
|

# ZW_CREATE_DEPDIR
|
||||
# ----------------
|
||||
# As AM_SET_DEPDIR, but also create the directory at config.status time.
