thanks for the patch, though it didn't work. all the hunks were already
applied in my glibc tree (with Bruno's patches).

however, the sysdeps/unix/bsd/bsd4.4/freebsd/i386/readelflib.c file looked
like an update of sysdeps/unix/bsd/bsd4.4/freebsd/readelflib.c. since i
don't know which of them has priority for Glibc, i overwrote the later,
but that didn't solve the linker problem.

on the other hand, i've found that the FreeBSD native linker does work
fine inside the chroot to load dynamic executables with Glibc, so i'm
using that for now.

I found more fun when linking stuff dynamicaly. many programs that worked
well as static like bash or ls now produce SIGBUS errors. did you had
this problem before? if there's no precedent, i'll go through debugging
it, there must be a wrong pointer use in some Glibc function.

also if you have more patches that are not in Bruno's site [1], or
know about more bugs, please tell about them so i can avoid repeating
your work.

P.S: i have perl! :) it basicaly works but segfaults (SIGBUS) when
running /usr/bin/dpkg-*
