Some platforms (namely HP-UX) require the 'x' bit set for shared libraries.

For performance reasons, it is also recommended to make the (mmap'ed)
shared library 'read-only'.
-> New permissions for installed shared libraries = 555

This doesn't hurt anybody, provided the installation is performed with
'cp -f' :-)
