first component is now a package name+version/pattern, no more
executable/patchname/whatnot.
While there, introduce BUILD_USES_MSGFMT as shorthand to pull in
devel/gettext unless /usr/bin/msgfmt exists (i.e. on post-1.5 -current).
Patch by Alistair Crooks <agc@netbsd.org>
binutils stuff (except gas) to a shared, multiple-target binutils build;
reduce extract and compile times by being more specific with files and
targets; update to egcs 1.1.1 with a diffball from NetBSD's src/gnu/dist
tree; add 4.4BSD a.out archive support to binutils.
