- acinclude.m4: make kernel-specific flags cacheable
-
- Specifically when cross-compiling, one can be willing to force these
- variable values using the environment of a config.cache file. This
- commit makes this possible.
-
- The affected variables are:
-
- * libzmq_cv_sock_cloexec
- * libzmq_cv_so_keepalive
- * libzmq_cv_tcp_keepcnt
- * libzmq_cv_tcp_keepidle
- * libzmq_cv_tcp_keepintvl
- * libzmq_cv_tcp_keepalive
