Port to Syllable : configure question

[Kristian Van Der Vliet]

Hi,

I'm currently porting Glibc to the Syllable operating system.  We already 
have a port of Glibc 2.1 which for various reasons, we are not going to 
maintain and cannot merge back into the main Glibc tree.  At the moment I am 
working with Glibc 2.3.2 on a Linux machine (Our port of GCC 3 is not 
complete yet, and 2.95 is too old)

It's coming on nicely at the moment but I have a problem.  Syllable has an 
"in kernel" ELF loader & RTLD, so we do not want anything that is in the elf/ 
directory (We probably don't want anything in dlfcn/ either, but that can 
wait).  I cannot simply set $elf=no as $elf implies all sorts of things that 
we do want.  What I have done so far is modify Makeconfig to:

# We have a special subdir for each binary format.
# For now, only ELF is fully supported.
ifeq ($(elf),yes)
# Syllable has a kernel ELF loader and uses its own libdl so we don't need
# to build any of the Glibc ELF stuff
ifneq ($(config-os),syllable)
binfmt-subdir = elf
endif
else
# This is probably better than nothing.
binfmt-subdir = aout
endif

..which means $(binfmt-subdir) is "" and the elf directory is not included as 
part of all-subdirs. This doesn't seem to work as I had hoped though, as 
after a while I still get the error:

The error "FATAL: can't create /home/user/glibc-configure/elf/soinit.os: No 
such file or directory" is quite correct; no ~/glibc-configure/elf/ 
diirectory is created for the object files to be placed, but obviously I 
don't want it to even try and build elf/soinit.c & friends at all.

At the moment I am groping my way around the Makefiles & configure scripts to 
try and catch the culprit, but I'm at a loss.  Is there something obvious I 
have missed, or do some Makefiles implicitly assume the elf directory, rather 
than using $(binfmt-subdir)?
