Well that's interesting, since I see it linking using -ldl, there must 
be some other setting that's affecting this, I have been looking in 
gnutls to see if I can find something else that sets libdl.so vs -ldl,
I have not found it.

configure:26075: i586-poky-linux-gcc -march=i586 
--sysroot=/builds/world/tmp/sysroots/qemux86 -o conftest -O2 -pipe -g 
-feliminate-unused-debug-types 
-I/builds/world/tmp/sysroots/qemux86/usr/include -Wl,-O1 
-Wl,--as-needed conftest.c  -ldl >&5
configure:26075: $? = 0
configure:26085: result: yes
configure:26092: checking how to link with libdl
configure:26094: result: -ldl

Sau!
