Yeah I wrote that .h file because nvidia's conftest.sh was stupid and
assumed linux == fedora.  Solved lots of problems at the time.

Also conftest.sh could not be run under module assistant with the
linux-headers-* only since module assistant wants to be able to do
a module build, and gives no option to run something else first that
mangles things.  conftest.sh really does seem like a crappy design.
