fix libtoolize scan of non-m4_include style aclocal.m4 [libtool--gary--1.0--patch-38..39]

[Gary V. Vaughan]

Okay to commit to HEAD?

        * libtoolize.m4sh (func_scan_files): When searching for  
evidence
        of Autotools in aclocal.m4, be careful not to trip over  
requires
        and defuns.

Cheers,
    Gary.
