HAVE_INITFINI_ARRAY check broken?

[Olaf Hering <olh at suse dot de>]

Hi,

it seems the check for HAVE_INITFINI_ARRAY is probably broken in 2.3.2,
on powerpc-linux:

configure:4802: checking for .preinit_array/.init_array/.fini_array support
configure:4815: gcc -o conftest conftest.c
                     -static -nostartfiles -nostdlib 1>&5
configure:4818: $? = 0
configure:4831: result: yes

The functionality is only implemented on ia64. The only package that
breaks is emacs:

The configure gcc run prints only a warning with gcc3.2.2, and succeeds
silently with gcc-3.3, the resulting conftest segfaults.
The string is there anyway:

mandarine:~ #     cat > conftest.c <<EOF
> int _start (void) { return 0; }
> int __start (void) { return 0; }
> int foo (void) { return 1; }
> int (*fp) (void) __attribute__ ((section (".init_array"))) = foo;
> EOF
mandarine:~ # gcc -o conftest conftest.c -static -nostartfiles -nostdlib
mandarine:~ # readelf -S conftest | fgrep INIT_ARRAY
  [ 3] .init_array       INIT_ARRAY      100100e0 0000e0 000004 00  WA  0   0  4
mandarine:~ # readelf -S conftest | fgrep INIT_ARRAY ; echo $?

What can be done?
