David,

I know I was abusing the make system, and I can see now that the original
Makefile might break if you did a make -j, but let me explain what I was trying
to do here.  Assume you are cross-compiling.

In the original Makefile, if sysconf_$(TARGET_ARCH).c is newer than sysconf.c,
it will be used. If it is older, then for the original Makefile you would get a
warning message, sysconf_$(TARGET_ARCH).c would not be changed, sysconf.c gets
copied to sysconf_src.c, and everything (should -- I couldn't test the
cross-compiling case) work.  Subsequent makes will continue to output the
warning message.

With you change, sysconf.c gets copied over sysconf_$(TARGET_ARCH).c on the
first make (if it is newer).  But now on subsequent makes, you don't see a
warning message and you may not think to rebuild sysconf_$(TARGET_ARCH).c.

Did this actually not build for you?

Manuel
