>Description:
Some packages that use  GNU_PROGRAM_PREFIX also install a symlink
if needed.
But they don't check if already exists!

if !defined(GNU_PROGRAM_PREFIX) || ${GNU_PROGRAM_PREFIX} != "g"
        ${LN} -s ${GNU_PROGRAM_PREFIX}m4 ${PREFIX}/bin/gm4

>How-To-Repeat:
Install gm4 or gmake with empty GNU_PROGRAM_PREFIX and file
or link already exists.
>Fix:
gtar-base
patch
gm4
gmake

Maybe ln should also use -f to force; or remove first.
