gnutls 3.1.0 build issues

[David Reiser]

Trying to build 3.1.0 in OS X using clang 4.0 from Apple's Xcode 4.4.1, 
configure gives me:

checking for tss library... no
configure: WARNING:
***
*** trousers was not found. TPM support will be disabled.
*** 

Neither the announcement nor the the docs that I can find mention a dependency 
on trousers. That probably should be corrected.

Since TPM support is disabled, I then see compiling stop with:

  CC     gnutls_supplemental.lo
system.c:442:10: error: use of undeclared identifier 'r'
  return r;
         ^
1 error generated.

because r is declared after gnutls determines that it is going to
return GNUTLS_E_UNIMPLEMENTED_FEATURE;

but clang is being ornery about the final 'return r;'
