Vacation 1.2.6.3 released

Missed this announcement, sorry!

This is a minor bugfix release to the 1.2.6 series of Vacation inspired by looking at the sorts of things Linux distros patch for their own usage.

Vacation no longer builds as -m486 by default, though it will build as 32-bit on AMD64/EM64T because GDBM is not 32/64-bit portable and trying to run a 64-bit version against a 32-bit created GDBM causes it to fail and syslog a success message. This is sub-optimal.

The Makefiles CFLAGS handling has been tidied up a fair bit as a consequence and will hopefully make life a little easier for distributors and it no longer tries to strip the vaclook Perl script on install, which was very silly.

Vacation also now accepts the -i option as well as -I to initialise its database.
