I have been unable to build libcruft for octave-2.1.xxx on irix6.5.
I have finally managed to find the problem and solve it.

System:  SGI Irix 6.5.3
Compilers:  gcc 2.95.1 (and others)
Make: GNU make 3.75 -> 3.78.1

Configure with

ac_cv_lib_elf_nlist=no  
ac_cv_lib_gen_getmntent=no
ac_cv_lib_sun=no
ac_cv_lib_sun_getpwnam=no
ac_cv_lib_sun_getmntent=no
ac_cv_lib_sun_yp_match=no
ac_cv_lib_socket=no
${SRCDIR}/configure \
    --enable-shared \
    --disable-static \
    --enable-lite-kernel \
    --enable-dlopen

Problem

Compilation of libcruft/misc/machar.o fails because special CFLAGS are not
passed to it

Real problem

With the above combination of configure options, and on Irix 6, the target
"all" in all the subdirectories of libcruft is empty.  The rule is

pic $(LIBCRUFT_DEPEND) $(CRUFT_PICOBJ) $(SPECIAL_PICDEPEND)

and each of the dependency macros is empty as SHARED_LIBS is true but
FPICFLAG is empty


Solution

The following patch to libcruft/Makerules.in solves the problem for me

*** libcruft/Makerules.in.0     Fri Oct 29 15:06:27 1999
--- libcruft/Makerules.in       Fri Oct 29 15:09:32 1999
