From: Andrew Ruder <andrew.ruder@elecsyscorp.com>
Subject: [PATCH] Disable tcl compatibility layers
Turn off building compatibility layers for old/broken versions of
standard functions (strstr, strtoul, strtod) with the assumption that
anything buildroot is using as a standard C library will be good enough
to not have broken behavior.
