apt-build additional features

[Ilia <inferrna@gmail.com>]

Is it possible to add new feature to apt-build for better optimization 
like this: custom additional CFLAGS for some packages that will be 
listed in separate config file. Smth like:
apt-build-cccflags.conf:
firefox '-O2'
geany '-O3 -flto'

For example, firefox couldn't be compiled with -flto, but others can.

And yes, I heard about gentoo, but it is very unstable and hard to manage.
