Severity: serious

dislocker is failing to build in Ubuntu because the Ubuntu autobuilder
environments are all "usrmerge" environments, where the /lib* directories
have all been moved to /usr and /lib* are just symlinks.

The consequence of this is that on architectures where the dynamic linker
has a path of /lib64/*, these files are now in /usr/lib64, and the existence
of this directory causes dislocker's upstream build system to misbuild,
trying to install the libraries to this target simply because this directory
exists.

This is wrong for multiple reasons, but the most immediately relevant is
that it simply causes the package to fail to build.

Please find attached a patch which corrects this issue.

Update: currently, dislocker fails to build on Debian too.
