distcheck fails

[sofar]

Due to extensive borrowing from systemd, the make distcheck target fails on make install due to DESTDIR not being properly preserved to include $$dc_install_base. I've spent some time trying to figure out how to coax it that way, but been unable to find the issue yet.

Making install in .
 /usr/bin/mkdir -p '/usr/lib/systemd'
  /bin/sh ./libtool   --mode=install /usr/bin/install -c systemd-bootchart '/usr/lib/systemd'
libtool: install: /usr/bin/install -c systemd-bootchart /usr/lib/systemd/systemd-bootchart
/usr/bin/install: cannot create regular file '/usr/lib/systemd/systemd-bootchart': Permission denied
