BR: pkgconfig(foo)

[Elan Ruusamäe]

hi

what's the opinion of using (for example) "BR: 
pkgconfig(gsettings-desktop-schemas)" instead of
"BR gsettings-desktop-schemas-devel"

i find it pretty convinient to fill deps this way, as mostly 
configure.ac requires those pkg-config names, not exact (rpm)packages

as for example, a build requires -only- *icon-theme.pc, but the .pc 
could be in main package (gnome-icon-theme) or -devel package 
(mate-icon-theme-devel), filling pkgconfig dep gets exactly there what 
is wanted, not as filling package name into dep

the pkgconfig deps are even versioned properly (code versions, not rpm 
versions), so can fill versioned dependencies without thinking which 
epoch is accurate.
