* depend2.am (@AMDEP@%FPFX%DEPMODE): Define it when GENERIC so
that it does not get noticed twice by automake, which now
complains for multiple definitions.
* tests/vartar.test: s/INSTALL/install/g, automake now complains
because we defined INSTALL.
I have strengthened the write permissions over the variables (well,
more accurately the existing rules are now applied to all the
variables thanks to macro_define, other cases were bugs IMHO, do to
too many specials cases). Therefore some things which were allowed
before must be fixed.
