[toplevel patch] Remove future variable name conflict in configure.in

[toplevel patch] Remove future variable name conflict in configure.in

[Nathanael Nerode]

This is the only variable name conflict with config-lang.in fragments.

It turns out that target_libs isn't used after its late assignment
from the config-lang.in fragments, which makes the assignment worthless,
so I just deleted it.

Tested on i686-pc-linux-gnu.

This is the precursor to simply sourcing the config-lang.in fragments
at the top level rather than running them through ungodly sed expressions.

	* configure.in: Rename 'target_libs' to 'target_libraries'.
	Remove useless reference to 'target_libs'.
	* configure: Regenerate.

Ok.
