This is almost certainly a libtool bug (sort of). The problem seems
to be that libtool is trying to make the library as it would
using AIX's cc, but you have CC=gcc.

I don't know enough about shared libraries on AIX to say what the
proper fix is here. I would suggest reporting this problem to
bug-libtool@gnu.org. 

As a workaround, you could try adding the "-shared" flag to 
the appropriate place in ltconfig. 

That is, before the {$wl}-bE.... in the following.

  aix4*)
    allow_undefined_flag=unsupported
    archive_cmds='$NM$libobjs | $global_symbol_pipe | sed '\''s/.* //'\'' > $lib.exp;$CC -o $objdir/$soname$libobjs ${wl}-bE:$lib.exp ${wl}-bM:SRE ${wl}-bnoentry;$AR cru $lib $objdir/$soname'
    hardcode_direct=yes
    hardcode_minus_L=yes
    ;;

It might convince gcc to not try to link in crt0.o.

If it is an option for you, you could try compiling with AIX's
compiler:

  CC=cc ./configure

(It really doesn't matter what version of libtool you have installed,
unless you want to upgrade the GTK sources to a newer version, but
1.0 is pretty old. GTK uses libtool-1.0f. libtool-1.0i is out on
alpha.gnu.org, I don't know if it fixes the problems in 1.0h.)
