webkit-gtk fails to build on a uclibc system because
Source/JavaScriptCore/wtf/Assertions.cpp assumes that all linux systems have
/usr/include/execinfo.h and provide backtrace().  But uclibc does not.  Its
straightforward to extend the test to see if its also a uclibc system and not
include execinfo.h or call backtrace()
