egl: Use -no-undefined libtool flag
egl: Use -no-undefined libtool flag

"Use -no-undefined to assure libtool that the library has no
unresolved symbols at link time, so that libtool will build a shared
library on platforms require that all symbols are resolved when the
library is linked."

If I had a dollar for every time I wrote this patch, I'd have about
$10 :-)
