maint.mk: sc_tight_scope: factor and support OS X
* top/maint.mk (_gl_tight_scope): Address three issues: - factor out four instances of code that wraps a string in "^...$" - allow nm-reported symbol names to have an optional leading "_" - add "main" to the list of ignored variable names, because on os x, "main" has nm-reported type "S" in the variable-checking section.
