oneapi: set -Wno-unused-command-line-argument (#33192)

Browse Source 
For older versions of intel-oneapi-compilers, running the compiler in
preprocessor / compilation mode would trigger warnings that
`-Wl,-rpath,...` flags were unused.

This in turn caused certain configure scripts to fail as they did not
expect output from the compiler (it's treated as an error). Notably
cmake's bootstrap phase failed to detect c++ features of the compiler.

As a workaround, add this flag to silence the warning, since I don't
think we can scope the flags to compile+link mode.
