Libtool adds -lc when it shouldn't

[Matthew John Warton]

Hi

I am trying to port gnu gettext to a research operating system called
mungi, using gettext's autoconf/libtool build environment

however there is no libc.a on this platform as of yet, which up until now
has not been a problem, however libtool is explicitly adding -lc to the ld
command line when I have tried to do everything possible to stop it.

The failure output from the specific section of make is as follows(excuse
the masses of compile flags):

/home/disy/crossdev/pc.i86.linux/lib/gcc-lib/mips64-elf/3.2/../../../../mips64-elf/bin/ld:
cannot find -lc
collect2: ld returned 1 exit status

as you can see, libtool is not given a -lc on its command line, yet it
issues one to ld.

In the configure I force the check for needing lc to fail by adding the
following line to the config cache:

archive_cmds_need_lc=no

Which is then properly propogated into the libtool script generated in the
directory.

I have tried tracing through the generated libtool script, but I cannot
see anywhere where -lc is explicitly added, except for one place which is
not executed as archive_cmds_need_lc is no, not yes as is needed for the
if statement (do a search for -lc and you will see what I mean)

Is there something basic I am missing here?  Is there another command
needed to overide this option?

Please let me know,

Matthew Warton
