>Description:
When compiling stuff with clang, and binutils-2.20 is installed,
ld may fail to create a eh_frame_hdr table (see last line in script below). The
system ld 2.15 does not complain.  Uninstalling binutils helps against getting
the error message, but since it's a dependency for gcc44/45/46 that I need for
other purposes, this isn't so easy.

Overriding PATH=/usr/bin:$PATH doesn't help.

>How-To-Repeat:

Run these commands:

# Install prerequisites
portmaster devel/binutils lang/clang devel/git devel/autotools

# Reproduce problem:
cd /var/tmp
git clone git://gitorious.org/fetchmail/fetchmail.git
cd fetchmail
autoreconf -isv
./configure '-C' '--with-ssl' '--with-gssapi' \
	'CFLAGS=-O2 -ggdb3 -Wall -Wextra -pedantic' 'CC=clang'
make -sj $(sysctl -n kern.smp.cpus)
rm fetchmail
make
# this should trigger the problem
