>Description:

If I do a "build.sh release" using sources extracted from source sets like
http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201203091940Z/source/sets/src.tgz
instead of sources directly checked out from CVS, the build fails:

    Making install in doc
    test -z "/usr/src/obj/tooldir.NetBSD-6.99.3-i386/share/info" || 
/usr/src/tools/gmp/../../external/lgpl3/gmp/dist/install-sh -c -d 
"/usr/src/obj/tooldir.NetBSD-6.99.3-i386/share/info"
    sh: /usr/src/tools/gmp/../../external/lgpl3/gmp/dist/install-sh: permission 
denied

Looks like the install-sh script is lacking execute permissions:

  $ zcat src.tgz | tar tfv - | grep gmp/dist/install-sh
  -rw-rw-r--  1 root     wsrc        9505 Jun 20  2011 
usr/src/external/lgpl3/gmp/dist/install-sh

The same script in a source tree checked out from CVS does have
execute permissions.

>How-To-Repeat:

See above.
