Subject: [PATCH] configure: Check for -Wno-error=format-truncation compiler
option
If this option is supported by compiler then disable it ( gcc7+)
+Use -Werror to elevate the warning to an error in case compiler like clang
+which warn about unknown options but not error out unless asked for
+
Fixes
client.c:834:23: error: '%s' directive output may be truncated writing up to 1023 bytes into a region of size 1010 [-Werror=format-truncation=]
