Yes, the HEAD version of libtool we use havent implemented -no-undefined for 
the gcc target. I did some experiments with it, but it seems adding support 
makes it impossible to build KDE since -no-undefined also disallows shared 
libraries that depend on other shared libraries, which is used extensively in 
KDE. (Apparently in ELF terms, symbols in an extern shared library are 
considered undefined)
