tinyproxy/configure.ac
Mukund Sivaraman abafcf08ab Remove the target system information when the version is displayed
If we require information about the runtime environment, it can be
found using the uname program. And binutils can tell about what the
tinyproxy binary contains. Tinyproxy doesn't have to report this
information.
