acinclude.m4 and m4/tcl.m4 both have underquoted macros in them, so this commit fixes them by properly quoting them. This also makes aclocal.m4 safe to regenerate with aclocal, which this commit does as well.

Regenerating aclocal.m4 with
aclocalis a standard part of an autotools workflow. All ofautomake,libtoolize, andgettextizetell you to do it, among others. However, the aclocal.m4 file in base contains some hard-coded macros in it, meaning that if you runaclocal, you're going to overwrite them and then be missing some of the macros you need. This PR fixes that by renaming the existing aclocal.m4 to acinclude.m4, and then fixing the "underquoted macro" warnings thataclocalproduces, so that a new aclocal.m4 can be regenerated safely.Closes: https://trac.macports.org/ticket/38579
