[Buildroot] [PATCH v10 1/4] Makefile: move LIB_SYMLINK definition to toolchain/helpers.mk

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

Commit 7a6b83a211612ff95a1f5d35b2861ad5655ac8b1 introduced the skeleton
package, which took over the lib32/lib64 -> lib symlink creation from the
main Makefile.
However, the definition of the LIB_SYMLINK variable did not move along, for
no real reason. At that moment, the most logical location for the definition
would be package/skeleton/skeleton.mk.

Given that due to a subsequent commit the definition will also be needed
from toolchain-external, move it instead to toolchain/helpers.mk which is
also conceptually a fine place.
