I wonder why we haven't been seeing this in our internal development
branch -- maybe because on that branch we're still discarding more
compiler options in the offloading path?
Committed to trunk in r220780:
commit 2fdc66a9fcfbc5b77c1c03d7c34893a0a086e8f8

nvptx-none: Define empty GOMP_SELF_SPECS.
Otherwise, offloading with -fopenacc or -fopenmp active will run into:
x86_64-unknown-linux-gnu-accel-nvptx-none-gcc: error: unrecognized
command line option '-pthread'

* config/nvptx/nvptx.h (GOMP_SELF_SPECS): Define macro.
