should suggest __section

Hi Joe,
While debugging:
we found a bunch of places where __section is not used but could be,
and uses a string literal when it probably should not be.

Just a thought that maybe could warn if
`__attribute__((section` appeared in the added diff, and suggest
__section? Then further warn to not use `""` for the section name?
