Component:  ports    |    Version:
 Keywords:           |       Port:  jq
---------------------+--------------------
 After upgrading to latest Xcode `jq` failed to build:

 {{{
 src/builtin.c:194:31: error: implicit declaration of function 'lgamma_r'
 is invalid in C99 [-Werror,-Wimplicit-function-declaration]
   jv ret = JV_ARRAY(jv_number(lgamma_r(jv_number_value(input), &sign)));
 }}}

 Applying the already present patch from `patch-src-builtin.c` eliminates
 the error and jq complies successfully.
