OK. You have installed nettle and nettle-devel but seems to be correctly 
recognized from 
pkg-config.

John D. pointed out that thing. From your config.log


configure:8470: checking for NETTLE

configure:8478: $PKG_CONFIG --exists --print-errors "nettle >= 2.7 nettle < 3.0"
Package nettle was not found in the pkg-config search path.
Perhaps you should add the directory containing `nettle.pc'
to the PKG_CONFIG_PATH environment variable
No package 'nettle' found
Package nettle was not found in the pkg-config search path.
Perhaps you should add the directory containing `nettle.pc'
to the PKG_CONFIG_PATH environment variable
No package 'nettle' found
configure:8481: $? = 1
configure:8496: $PKG_CONFIG --exists --print-errors "nettle >= 2.7 nettle < 3.0"

to the PKG_CONFIG_PATH environment variable
No package 'nettle' found

to the PKG_CONFIG_PATH environment variable

configure:8499: $? = 1

configure:8527: result: no
configure:8530: error: 
  ***
  *** Libnettle 2.7.1 was not found. Note that this version of gnutls doesn't 
support nettle 3.0.

The above obviously shows that pkg-config does not work correctly. 
It must be corrected if you want to improve the situation.
Therefore I have sometimes asked you where (a) file(s) nettle.pc is (are). 


Please search where nettle.pc if you do not know it.  
$ find / -name nettle.pc

and show the results here
