Enable multiarch (32/64-bit co-installation)
It is currently not possible to have 32- and 64-bit builds of beignet
installed on the same system, as the path in intel-beignet.icd
can only be one of the two installations. This fixes this by giving
this file a different name when beignet is installed in a multiarch
directory:
intel-beignet-i386-linux-gnu.icd -> /usr/lib/i386-linux-gnu/beignet/libCL.so
intel-beignet-x86_64-linux-gnu.icd -> /usr/lib/x86_64-linux-gnu/beignet/libCL.so
Discussion and possible alternative approaches:
http://lists.alioth.debian.org/pipermail/pkg-opencl-devel/Week-of-Mon-20150223/date.html
While preparing this patch I noticed that intel-beignet.icd.in
uses @LIB_INSTALL_DIR@/beignet/ rather than @BEIGNET_INSTALL_DIR@,
which will obviously break if the latter is set directly. Is
that a bug or is this intended to be an internal-only variable?
