Hello,

In Packages-arch-specific, please remove any limits for "prelink", as it
is arch-agnostic (it is an ELF parser).  Attached is a patch...

Thanks,

-Kees

As far as I know, it does need to know arch specific things.  It
needs to know about the different relocation types which depend
on the arch.  It seems to have those files in the src/ dir:
-rw-r--r-- 1 kurt kurt 13514 Mar 10 18:53 arch-alpha.c
-rw-r--r-- 1 kurt kurt 22973 Mar 10 18:53 arch-arm.c
-rw-r--r-- 1 kurt kurt 10669 Mar 10 18:54 arch-cris.c
-rw-r--r-- 1 kurt kurt 28465 Mar 10 18:54 arch-i386.c
-rw-r--r-- 1 kurt kurt 13604 Mar 10 18:54 arch-ia64.c
-rw-r--r-- 1 kurt kurt 31290 Mar 10 18:54 arch-mips.c
-rw-r--r-- 1 kurt kurt 30357 Mar 10 18:56 arch-ppc.c
-rw-r--r-- 1 kurt kurt 23600 Mar 10 18:55 arch-ppc64.c
-rw-r--r-- 1 kurt kurt 13578 Mar 10 18:56 arch-s390.c
-rw-r--r-- 1 kurt kurt 16388 Mar 10 18:56 arch-s390x.c
-rw-r--r-- 1 kurt kurt 11531 Mar 10 18:56 arch-sh.c
-rw-r--r-- 1 kurt kurt 17928 Mar 10 18:57 arch-sparc.c
-rw-r--r-- 1 kurt kurt 24368 Mar 10 18:56 arch-sparc64.c
-rw-r--r-- 1 kurt kurt 14460 Mar 10 18:57 arch-x86_64.c

But I don't know if all those arches have been tested and
work properly.  It's also missing support for hppa.

The source also contains:
Architecture: alpha amd64 i386 powerpc ppc64

So you would atleast need to change that first.  There is atleast
an open bug for mips/mipsel (#497328) for it.

Ah, very true, sorry I missed that.

I've tested that at least execstack works on armel.

Since it has an explicit Arch list, it seems to make sense to drop prelink
from P-a-s?

Please update the package first.  Then we can arrange that it
gets built everywhere except hppa.
