Providing parameters to `.` when sourcing is a bashism and not supported
by POSIX shell which causes a build failure when compiling a toolchain
for nvptx-none with dash as /bin/sh.
gen-copyright.sh takes a parameter for the format of copyright notice
required. Switch that to using an environment variable `NVPTX_GEN_COPYRIGHT`,
although this could be changed to a function if desired (just more churn
in gen-copyright.sh then).
gcc/ChangeLog:
PR target/117854
* config/nvptx/gen-copyright.sh: Read NVPTX_GEN_COPYRIGHT envvar.
* config/nvptx/gen-h.sh: Set NVPTX_GEN_COPYRIGHT.
* config/nvptx/gen-opt.sh: Ditto.

Testing it now with a build for nvptx-none. Is this approach OK or
would you prefer the function approach (which will make the diff larger
because of reformatting)?
