# There are no architecture-independent files to be uploaded

# XXX This isn't entirely true - all the .int files (and such)
# are architecture independent. But that's not really worth worrying
# about.

# To build the binary package, we install into ./debian/tmp/usr
# However, we have configured as if we are going to install into
# /usr, so we need to convince the "make install" target to
# install elsewhere.
# We override INSTALL_PREFIX to tell it to install to ./debian/tmp/usr.
# Hardcoded paths should be depending on FINAL_INSTALL_PREFIX instead,
# which we leave configured for /usr.
