>Description:
The package "x11/qt5-qtbase" fails to build in FreeBSD 11.0-RELEASE due to a link time error because of an undefined reference to "kinfo_getproc"

Partial build output:

libtool --silent --mode=link clang++ -lexecinfo -L/usr/lib -Wl,-R/usr/lib -L/usr/pkg/lib -Wl,-R/usr/pkg/lib -pthread -Wl,-rpath,/usr/pkg/qt5/lib -o ../../../bin/qlalr .obj/compress.lo .obj/cppgenerator.lo .obj/dotgraph.lo .obj/lalr.lo .obj/main.lo .obj/parsetable.lo .obj/recognizer.lo .obj/grammar.lo   -L/usr/pkg/lib -L/usr/lib -L/usr/pkgsrc/x11/qt5-qtbase/work/qtbase-opensource-src-5.5.1/lib /usr/pkgsrc/x11/qt5-qtbase/work/qtbase-opensource-src-5.5.1/lib/libQt5Core.la -lexecinfo -lpthread -lrt

>How-To-Repeat:
1. Get current pkgsrc via CVS 
2. Prepare and bootstrap pkgsrc in FreeBSD 11.0-RELEASE
3. cd x11/qt5-qtbase && bmake
4. After sometime the build fails with the link time error mentioned in the "Full description".
>Fix:
The undefined reference to "kinfo_getproc" can be solved by giving the linker -lutil flag. This can be done by modifying the existing Makefile.

Steps to fix

1. Apply the following patch in x11/qt5-qtbase 

Index: Makefile
