>Description:
If you by some freak accident have got devel/binutils installed,
then the pkgsrc wrapper framework will automatically prefer
the broken /usr/pkg/bin/ld over the native ld(1).


>How-To-Repeat:
# cd /usr/pkgsrc/pkgtools/digest
# touch /usr/pkg/bin/ld
# chmod +x /usr/pkg/bin/ld
# export PATH=/bin:/usr/bin
# make
[...]
configure: error: C compiler cannot create executables

grep "^cmd=" work/.wrapper/bin/ld
cmd="/usr/pkg/bin/ld"
cmd="$cmd $libs"

>Fix:
pkgsrc should probably not look in ${PREFIX} for toolchain components.
Also, devel/binutils should use GNU_PROGRAM_PREFIX="pkgsrc-" or something like 
that.
