Bug#991592: nvidia-cuda-toolkit: NVVMIR_LIBRARY_DIR on ppc64le points to wrong location

[Alex Waite]

Source: nvidia-cuda-toolkit
Version: 9.2.148-7
Severity: important

The contents of /etc/nvcc.profile on ppc64le seem to be incorrect, where the
following default is defined:

NVVMIR_LIBRARY_DIR = $(TOP)/nvvm/libdevice

This location resolves to a location that doesn't exist
(/usr/lib/nvidia-cuda-toolkit/bin/../nvvm/libdevice/) and causes compilation to
fail (and I assume other task as well):

> nvcc $1 -o ~/bin/$1.lx_ppc -O3 -std=c++11 -lgsl -lm -lgslcblas
error in open: /usr/lib/nvidia-cuda-toolkit/bin/../nvvm/libdevice/libdevice.10.bc

The correct location is /usr/lib/nvidia-cuda-toolkit/libdevice

Additional paths also seem to be incorrect, including LD_LIBRARY_PATH, INCLUDES,
and PATH.

At first glance, /usr/lib/cuda/ seems to be the correct target for TOP, as the
folder hierarchy looks similar. However, it doesn't actually match what
nvcc.profile defines and most folders are empty.

The following fixes my current blockers (compilation), but I assume the complete
fix will require fixing all values in /nvcc.profile:

NVVMIR_LIBRARY_DIR = /usr/lib/nvidia-cuda-toolkit/libdevice
