You are building with make -j 1 ? I don't build all of those
packages, but on my Intel i3-2120 (SandyBridge, low-end) with make
-j4 I get:
firefox (without xulrunner) 3130 seconds
qt 2413 seconds
but libreoffice 15269 seconds (not as full a build as I had intended,
"only" 55 languages - I missed a few) I guess you are only doing an
English build :)
Also, your firefox build looks as if something is wrong in your
mozconfig - with xulrunner already built, firefox should only take a
few minutes, even with make -j 1. There was a similar issue noted a
few months ago, and I then hit it. ISTR it was to do with our old
method of NOT quoting EOF when creating mozconfig, together with
some variable escapes. Or perhaps you didn't uncomment the lines to
use system libxul.
But yes, it gets slower with every new toolchain version, and many
desktop upgrades bring in extra dependencies.
das eine Mal als Tragödie, dieses Mal als Farce
