bump PKGREVISION where necessary
Move PKG_TEXMFPREFIX and PKG_LOCALTEXMFPREFIX definitions to
teTeX?/buidlink3.mk, so that packages may include
print/teTeX1-bin/buildlink3.mk directly (however, using teTeX/module.mk do not
allow that)
It includes the correct buildlink3.mk file from either
teTeX1 (print/teTeX1-bin), teTeX2 (print/teTeX-bin) or teTeX3
(print/teTeX3-bin). tex.buildlink3.mk will:
* set PKG_TEXMFPREFIX to the base directory of the used texmf tree
* set PKG_LOCALTEXMFPREFIX to the base directory of the local texmf
tree (for tex packages)
* set LATEX_TYPE to the latex distribution used.
There are two variables that can be used to tweak the selection of
the latex implementation:
LATEX_DEFAULT is a user-settable variable whose value is the default
latex distribution to use.
LATEX_ACCEPTED is a package-settable list of latex distributions
that may be used by the package.
