<pre>To reproduce, install strace and run:
echo "int main(){}" | strace ./bin/clang -x c -o /dev/null -
One my system, I get, 10 access() syscalls looking for ptxas, and 4 stat()
syscalls looking for a cuda install.
It would be nice it we could eliminate the filesystem searches, since the
aren't necessary, and can reduce compile time performance especially on systems
with slow or network mounted filesystems.</pre>
