build: accommodate -Werror=suggest-attribute=pure
Now that we're using the latest manywarnings module from gnulib,
accommodate gcc's -Werror=suggest-attribute=pure option by marking
suggested functions with gnulib-defined _GL_ATTRIBUTE_PURE.
* src/kwset.c (hasevery): Mark function with pure attribute.
(bmexec): Likewise.
* src/dfa.c (nsubtoks, istrstr, find_pred, dfamusts): Likewise.
* configure.ac: Disable (for lib/) options that seem not to be worth
the trouble: -Wunsuffixed-float-constants and -Wformat-nonliteral.
