```
% ./xbps-src show-options execline
=> execline-2.6.1.0_1: the following build options are set:
   static: Enable static linking (OFF)

% echo "XBPS_PKG_OPTIONS_execline=static >> etc/conf

% ./xbps-src show-options execline
=> execline-2.6.1.0_1: the following build options are set:
   static: Enable static linking (ON)
```
This looks more like a problem of `execline` not honoring the build option than an XBPS issue.
