Hi,
This patch detects PIE binaries with newer file (5.22), as
it no longer prints (uses shared libraries)
file 5.19
# file /usr/bin/su
/usr/bin/su: setuid ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 3.0.0,
BuildID[sha1]=c22b7c2ca90323d07e30d742e97c08bb98313d8a, stripped
file 5.22
# file /usr/bin/su
/usr/bin/su: setuid ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux
3.0.0, BuildID[sha1]=030ed4b9e0129d19842cd0e3cbebbc614417d748, stripped
Ciao, Marcus
