[gentoo-dev] new virtual/pkgconfig to support lighter alternatives

[Mike Frysinger]

the canonical pkg-config is getting fat.  it requires glib-2.  it runs pkg-
config when building.  glib-2 requires pkg-config.  whee.

for our normal systems, this isn't a big deal.  but we'd like to enable a 
lighter alternative for embedded/alternative systems.  as such, i'd like to 
introduce a virtual/pkgconfig that allows for selection of simpler (but 
compatible) implementations.

we've got an implementation in perl (i'm not interested in), but there is also 
"pkg-config-lite" and "pkgconf".  they should be compatible with the canonical 
pkg-config.  they aren't yet in the tree, but will be once we agree on this 
topic.

any comments ?
