TODO: update

Add TODO list for m4, autoconf, automake and libtool.
Building our own versions would remove burden from the users
who have older versions on their distributions, and are not
ready/able/allowed to upgrade.
     1 Original patch from Gentoo.

     3 -= BEGIN original header =-
     4 ARMV5 can use STRD and LDRD access instructions but these accesses need to be 
     5 8 byte aligned. The dynamic linker's malloc needs to match this so structures
     6 become 8 byte aligned to void unaligned accesses.
