srcu: Avoid escaped section names

The stringification operator, `#`, in the preprocessor escapes strings.
For example, `# "foo"` becomes `"\"foo\""`.  GCC and Clang differ in how
they treat section names that contain \".
The portable solution is to not use a string literal with the
preprocessor stringification operator.
