nettle: add nettle to oe-core

Newer versions of gnutls depends on nettle.
Any idea why it fails in some builds like this:

| checking whether ln -s works... yes
| checking build system compiler gcc ... no
| configure: error: Specified CC_FOR_BUILD doesn't seem to work
| Configure failed. The contents of all config.log files follows to aid 
debugging
| ERROR: oe_runconf failed
| WARNING: exit code 1 from a shell command.

config.log:
configure:4412: checking build system compiler gcc
configure:4425: gcc  conftest.c
conftest.c: In function 'main':
conftest.c:4:3: warning: incompatible implicit declaration of built-in function 
'exit' [enabled by default]
    exit(0);

configure:4435: result: no
configure:4440: error: Specified CC_FOR_BUILD doesn't seem to work

export CC_FOR_BUILD="gcc "


I suspect the crosscompiler; for what arch&machine does this fail?
