configure: add -lm to configure for rustls build.
Note: The list of libraries that rustc tells us we need to include is
longer, but also includes some more platform-specific libraries that I
am not sure how to effectively incorporate. Adding just -lm seems to
solve an immediate problem, so I'm adding just that.

Closes #8002
