patch 9.0.0103: if running configure with cached results -lrt may be missing Commit: https://github.com/vim/vim/commit/efffa5360ebb2b6919c5eb1998c5df4c8849a407 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Jul 28 22:39:54 2022 +0100 patch 9.0.0103: if running configure with cached results -lrt may be missing Problem: If running configure with cached results -lrt may be missing. Solution: Use two cache variables, one without and one with -lrt. (closes #10799) Swap checks to avoid adding -lrt unnecessarily.
