[Ltib] how to compile an ltib-format app dir without using ltib?

[Robert P. J. Day]

  for reasons i don't have time to get into, i'd like to be able
to just compile a source directory that's been set up to be built
by ltib, but do it without actually invoking ltib.  to this end,
i'm trying to invoke the "spoofed" wrappers directly, and setting
up all of the shell environment beforehand so that i am effectively
invoking that spoof wrapper with everything it would normally expect
to see if it had been called via ltib.

  to that end, i've set up a little script file that i can source
to establish what i think are the appropriate environment variables
thusly:

==========

export  
TOOLCHAIN_PATH=/opt/freescale/usr/local/gcc-4.1-glibc-2.3/m68k-glibc/freescale-coldfire-4.1

PATH=${TOOLCHAIN_PATH}/m68k-linux-gnu/bin:${PATH}
PATH=${TOOLCHAIN_PATH}/libexec/gcc/m68k-linux-gnu/4.1.1:${PATH}

export TOOLCHAIN_FLAGS="-mcf4ve"
export TOOLCHAIN_PREFIX=m68k-linux-gnu-

export DEV_IMAGE=<rootfs directory>

==========

  note that what i'm trying to do above is to set the env info
just the way spoof_wrapper expects to see it from ltib.  there's the
TOOLCHAIN_PATH, followed by a couple prepends to PATH to find gcc
and cc1, respectively.  i've explicitly added the flags and prefix
that spoof_wrapper, and one more for DEV_IMAGE.

  at that point, i go to the source directory and, rather than
using ltib, i just type "make all", at which point i get:

xxx.c:41:19: error: ctype.h: No such file or directory
In file included from xxx.c:42:
xxx.h:15:20: error: stdlib.h: No such file or directory
xxx.h:16:18: error: time.h: No such file or directory
xxx.h:17:20: error: limits.h: No such file or directory
xxx.h:84:20: error: stdarg.h: No such file or directory
... etc etc ...
make[1]: *** [obj/wildmat.d] Error 1
make: *** [all] Error 2

  what i'm *assuming* is that the m68k cross-compiler is being
invoked properly, as is cc1.  but the header file include
path is not set properly.  i'm assuming that the standard headers
that should be pulled in are from the cross-compiler toolchain,
and would be found in the appropriate directory under
/opt/freescale/...  and so on.  but obviously that's not happening.

  i've verified that the cross-compiler gcc is being called, now
i just need to figure out how to get it to look at its *own*
header files.  thoughts?
