OK, my apologies for misunderstanding. I won't have time to look through
your files tonight, I'll try to take a look and respond in more detail
tomorrow.
In the meantime you might want to try out a Free Software tool called
remake which is basically a modified version of GNUmake that adds flags
that allow you to debug and step through Makefiles. I use it
occasionally and it can help to understand what's going on, although the
EPICS build system is somewhat complex (!).
One other technique I use is a PRINT rule that I have in my personal
~/configure/RULES_USER file. This file is read in towards the end of
*every* EPICS build that I do from my account, so be careful what you
put in there (there are similar ~/configure/CONFIG_USER.* files also
supported by the builsd system). Here's my file:
> tux% cat ~/configure/RULES_USER

Inside an O.<arch> directory I can type 'make PRINT.<varname>' and it
shows me the value of that variable, e.g:
> tux% cd O.RTEMS-uC5282/
> tux% make PRINT.OS_CLASS
> make -f ../Makefile TOP=../.. T_A=RTEMS-uC5282 PRINT.OS_CLASS
> make[1]: Entering directory '/home/phoebus3/ANJ/epics/base/3.15/configure/O.RTEMS-uC5282'
> OS_CLASS = 'RTEMS'
> make[1]: Leaving directory '/home/phoebus3/ANJ/epics/base/3.15/configure/O.RTEMS-uC5282'
