Template initialization on OSX master

[Alexander Thurgood]

Since master build 342b1895d768dc633c3067df6618cd3567b72a6d

I am seeing a whole load of the following error messages on startup (one
for each template) :

warn:tools.urlobj:10469:1:tools/source/fsys/urlobj.cxx:1739: cannot make
<../AbstractGreen.otp> absolute against broken base <>
warn:tools.urlobj:10469:1:tools/source/fsys/urlobj.cxx:1739: cannot make
<../AbstractRed.otp> absolute against broken base <>
warn:tools.urlobj:10469:1:tools/source/fsys/urlobj.cxx:1739: cannot make
<../AbstractYellow.otp> absolute against broken base <>

I am building with the --enable-extra-template switch
