toolchain/crosstool-NG: correctly copy the dynamic linker

Depending on some setting (which? Arch? Others?), the dynamic linker
can get different names. Some times, it is named ld-linux.something.so,
other times, it is ld.so.1, and maybe other variants as well...

The fix is to always copy ls*.so, even if it is a symlink: we create
the destination file by its SONAME, and if ld*.so matches more than
one file, that's no issue, as they would all get the same SONAME (being
symlinks ones to the others).

Split long lines at the same time.
