libtoolize: select the first directory from AC_CONFIG_MACRO_DIRS.

* tests/libtoolize.at (multiple AC_CONFIG_MACRO_DIRS directories):
New test to ensure multiple directory arguments mork correctly.
* libtoolize.in (func_require_ac_macro_dir): Use expr to discard
any additional space delimited entries in the first
AC_CONFIG_MACRO_DIRS argument.
* bootstrap (func_require_macro_dir): Likewise.
