Subject: binutils-config: fix native link removal by cross-compilers, bug
 #724454

commit 36eba05752348258a7 ("binutils-config: add build-time
and runtime switches to disable native symlinks").

Added symlink deletion for USE_NATIVE_LINKS=no mode.
It had a bug: it unconditionally deleted native symlinks
if binutils-config is called on a cross-binutils installation.

I missed the case because I assumed that tool names
in binutils' private directory match gcc' private directory.

The change is not to perform symlink cleanup for unprefixed
binaries for cross-binutils.
