Re-enable building position-independent executables on Linux/*BSD
Re-enable building position-independent executables on Linux/*BSD

This provides better security at the cost of having misleading
binary icons on some file managers.

Now that recent Linux distributions no longer allow executing
binaries by double-clicking them in a file manager (even if the
binary is set to be executable), the usability cost of PIE is lowered.
You have to use a terminal or install a `.desktop` file nowadays.
