libtool: Remove test_compile

Browse Source 
This is cleanup for libtool. The option test_compile is not used in
libtool, and the documentation states that it would probably be dropped
in the future.

* build-aux/ltmain.in: Remove case statement for test_compile.
* doc/libtool.texi: Remove test_compile from documentation.
* m4/libtool.m4: Remove test_compile definition from macro file.
