# Why the nastyness? linuxdeploy strips our main binary, and there's no option to turn it off.
# It also doesn't strip the Qt libs. We can't strip them after running linuxdeploy, because
# patchelf corrupts the libraries (but they still work), but patchelf+strip makes them crash
# on load. So, make a backup copy, strip the original (since that's where linuxdeploy finds
# the libs to copy), then swap them back after we're done.
# Isn't Linux packaging amazing?
