How to recompile 'gcc-4.9-4.9.2' package with different prefix?

[Valeriy Solovyov]

Can I use something like this:

apt-get build-dep -y gcc-4.9-multilib apt-get source -y gcc-4.9-multilib
dpkg-source -x gcc-4.9_4.9.2-0ubuntu1~12.04.dsc cd gcc-4.9-4.9.2
*PF=opt/dev-tools-4.9* dpkg-buildpackage -rfakeroot -b

Or this:

apt-get build-dep -y gcc-4.9-multilib apt-get source -y gcc-4.9-multilib
dpkg-source -x gcc-4.9_4.9.2-0ubuntu1~12.04.dsc cd gcc-4.9-4.9.2

tar -xf gcc-4.9.2.tar.xz

cd gcc-4.9.2
