Bug#920894: Bug#918329: apriltag ftbfs on release architectures

[Matthias Klose]

The README even says:

Install
=======

The default installation will place headers in /usr/local/include and
shared library in /usr/local/lib. It also installs a pkg-config script
into /usr/local/lib/pkgconfig. Be aware that there are some larger tag families
which may take a long time to build. If you do not want to use these tag
families then you can speed up the installation by deleting the files
tagCircle49h12.c, tagCircle49h12.h, tagCustom48h12.c, tagCustom48h12.h,
tagStandard52h13.c, and tagStandard52h13.h before installing.
