>Description:
In devel/scmgit-base (as an example) I did
bmake wrapper

I created a file
> cat test.c
int main() {
};

The file compiles and links in this way 
(in this way linker is checked in  ./configure of devel/scmgit-base)
> ./work/.wrapper/bin/gcc -R / test.c

But it gives error if I add ${LOCALBASE}/lib as an argument
> ./work/.wrapper/bin/gcc -R/home/vital303/netbsd/lib test.c
gcc: error: unrecognized option '-R'

If I link directly with gcc I get errors
> gcc -R/home/vital303/netbsd/lib test.c
gcc: error: unrecognized option '-R'

> gcc -R /  test.c
gcc: error: unrecognized option '-R'

My gcc version is
gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1

>How-To-Repeat:
bmake install in
devel/scmgit-base

for gcc with no -R option
>Fix:
For devel/scmgit-base I add
CONFIGURE_ENV+=         git_cv_ld_dashr=no
to devel/scmgit-base/Makefile
