Bug 1333333

Description of problem:
Rpm test suite stopped working with the version fakechroot-2.17.2-1.fc22, it worked fine with the previous released version fakechroot-2.9-32.fc22. The problem is that dlopen() can't open libraries outside of fake root now. Have a look at the minimal reproducer in the steps to reproduce section.


Version-Release number of selected component (if applicable):
fakechroot-2.17.2-1


How reproducible:
always


Steps to Reproduce:
# mkdir -p test`rpm -E %_libdir`
# cd test
# cat <<'EOF' > test.c
> #include <dlfcn.h>
> 
> int main()
> {
>     void *handle;
>     void (*printFoo) (void);
> 
>     handle = dlopen("libtest.so", RTLD_LAZY);
>     printFoo = dlsym(handle, "printFoo");
>     printFoo();
> 
>     return 0;
> }
> EOF
#
# cat <<'EOF' > libtest.c
> #include <stdio.h>
> 
> void printFoo()
> {
>     printf("foo\n");
> }
> EOF
#
# gcc -ldl -o test test.c
# gcc -shared -fPIC -o libtest.so libtest.c
# mv libtest.so `rpm -E %_libdir`
# ldconfig
# export LD_LIBRARY_PATH=`pwd``rpm -E %_libdir`
# export FAKECHROOT_BASE=`pwd`
# 
# # With fakechroot-2.9-32.fc22 you have following output
# fakechroot ./test
foo
#
# # but after update to fakechroot-2.17.2-1.fc22
# fakechroot ./test
/usr/bin/fakechroot: line 213: 18761 Segmentation fault      (core dumped) LD_LIBRARY_PATH="$fakechroot_paths" LD_PRELOAD="$fakechroot_lib" "$fakechroot_cmd" "${@:2}"


Actual results:
It seems that a fakechrooted binary can't dynamically load a library which is outside of a fake root. 


Expected results:
A fakechrooted binary should be able to load a library from outside of a fake root because it was able to do that with previous versions of fakechroot,
