I see that this is being somehow caused by using a new version of gcc,
but I have no idea what could be causing it. gcc creates the shared
libraries in the usual way, and an ordinary shared library should not
fail with an EACCES error. I have no idea what could cause that.
You may get farther if you ask people familiar with GNU/Linux or with
the dynamic linker, which on Debian is part of glibc or eglibc.
