Subject: environment variables in ld scripts

I have inherited an application that makes extensive use of ld scripts.  The former developer hard-coded many absolute directory paths into these scripts, e.g.:

-L /home/harold/libs -( -lnwiss -lr -)
@/home/harold/libs lib.ld

I would like to use environment variables so that I can use, say /home/jay/ rather than /home/harold.  So I'll define:

export APP_LIBS=/home/jay/libs

but neither of the following works:

-L $APP_LIBS -( -lnwiss -lr -)
@$APP_LIBS lib.ld

Is there a special notation for employing environment variables in ld scripts?

Thanks,
Jay
