What happens if you run the following shell script?  If it dumps core,
your linker is broken.

#! /bin/sh

mkdir /tmp/t.$$  || exit 3
cd /tmp/t.$$     || exit 3

cat >main.c <<'EOF'
#include <stdio.h>
#include <dlfcn.h>

int main(void)
{
    void *handle, *sym;
    char *error;

    puts("calling dlopen");
    handle = dlopen("./dyn.so", RTLD_NOW);
    if (!handle) {
        printf("%s\n", dlerror());
	return 1;
    }

    puts("calling dlsym");
    sym = dlsym(handle, "sym");
    if ((error = dlerror()) != 0) {
        printf("%s\n", error);
	return 1;
    }
    puts("calling sym");
    ((void (*)(void))sym)();
    puts("done");
    return 0;
}
EOF

cat >dyn.c <<'EOF'
#include <stdio.h>
void sym(void)
{
    puts("in sym");
}
EOF

[ -n "$SHFLAGS" ] || SHFLAGS="-fPIC -shared"

set -x

$CC $CFLAGS $SHFLAGS dyn.c -o dyn.so
$CC $CFLAGS main.c -o main -ldl

./main || exit $?

cd /tmp
rm -rf t.$$
