[tlbuild] some executable inconsistencies

[Vladimir Volovich]

Hi!

i've noticed the following things, some of which might need to be
corrected (especially those marked with (*) below):

=====================================
i386-freebsd, amd64-freebsd:
     missing: tcdialog

i386-kfreebsd, amd64-kfreebsd:
 (*) "xasy" is a symlink to "asy", instead of to "../../texmf/asymptote/GUI/xasy.py"
     missing: tex2xindy, texindy, xindy.mem, xindy.run, xindy

i386-cygwin:
 (*) missing symlink: xasy -> ../../texmf/asymptote/GUI/xasy.py

i386-solaris, powerpc-aix, sparc-linux, sparc-solaris, x86_64-solaris:
     missing: asy, xasy

mips-irix:
 (*) very outdated
=====================================

also, as of now, some architectures need to be rebuilt, based on
comparing the revision when xetex source was updated, and the revision
of xetex binary (19401):

$ svn log Build/source/texk/web2c/xetexdir/xetex.ch | head
------------------------------------------------------------------------
r19401 | jonathan | 2010-07-12 20:21:35 +0400 (Mon, 12 Jul 2010) | 1 line

xetex 0.9997.4, fix segfault in \XeTeXdelcode
------------------------------------------------------------------------
...

Path: Master/bin/powerpc-aix/xetex Last Changed Rev: 19418
Path: Master/bin/sparc-solaris/xetex Last Changed Rev: 19419

this means that at least xetex is outdated in mips-irix through
i386-netbsd in the above list, but likely some other binaries too.

Best,
