>Environment:
Interix nile 3.5 SP-8.0.1969.1 x86 AMD Athlon/Duron
>Description:
When executing "bmake install" for a package which doesn't have DEPENDS
(i.e., devel/patch), following message is displayed.

pkg_info: missing package name(s)
usage: pkg_info [-BbcDdFfIikLmNnpqRrSsVvh] [-e package] [-l prefix]
                pkg-name [pkg-name ...]
       pkg_info -a [flags]
       pkg_info -Q variable pkg-name [pkg-name ...]

This is caused by the different behavior of xargs command. Interix's xargs
executes the command that is given as arguments even when standard input
is empty.

>How-To-Repeat:
cd /usr/pkgsrc/devel/patch
bmake install

>Fix:
This is a patch for bsd.bsd.mk.
