[PATCH] sudo: Compile mksigname and mksiglist for build host

[Khem Raj <raj.khem@gmail.com>]

cross compiling sudo doesnt work well since it uses
mksigname and mksiglist to generate C sources which
are then used in sudo build itself. With this patch
now we make sure those hosttools are compiled for
build machine. It fixes the build failures like

./mksigname > signame.c
/bin/sh: ./mksigname: cannot execute binary file
make[1]: *** [signame.c] Error 126
