build/autotools errors with libtool 2.4.7

[Rudi Heitbaum]

Hi Alex,

I look after the package currency for LibeELEC, and ran though testing
the latest libtool 2.4.7 release in LibreELEC.

a couple issues:

The tar.gz file has ltmain.sh as readonly. I fixed this in our build with the
workaround: chmod u+w ${PKG_BUILD}/build-aux/ltmain.sh (after unpack and
before patch)

The autotools build fails - more details below. Though I was able to test 
the full build by editing aclocal.m4 and changing automake from 1.16.3 to 
1.16.5 (we use automake 1.16.5). The build was sucessful.

Using our current 2.4.6 package.mk file results in the build log as below.
(libltdl/ltdl.mk is removed and doesnt rebuild, also ltversion.in)

Regards
Rudi
