- drop x-hacks for curl internal variables and certain autotools ones that do not hold custom values. - make x-hacks consistently use `"x$var" = "xval"` style. - add a few x-hacks for input/external variables that may hold custom values. - prefer `-z` and `-n` to test empty/non-empty. This also makes some x-hacks unnecessary. - optimized negated test `-z` and `-n` options. - prefer `&&` and `||` over `-a` and `-o`. For better POSIX compatibility: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html - quote variables passed to `test`, where missing. - quote string literals in comparisons. - fix some indentation, whitespace. Note that a few `case` statements also use the x-hack, which looks unnecessary. This patch does not change them. Verified by comparing feature detection results with a reference CI run from before this patch (PR #19922).
