ebuild-env-vars.tex: D is available as a variable in all src_* phases
The D variable has been described as a "phase-specific variable" since
the spec's early draft stage (SVN r19). However, Portage would always
define the variable in all src_* phases, with the restriction that the
directory would exist only in src_install().
In reality, not all ebuilds comply with the spec. For example, Perl
eclasses use D in src_configure(), i.e. they rely on Portage behaviour.
Therefore, lift this unnecessary and somewhat artificial restriction
and make the variable (but not the directory) available outside the
install phase.
