[CentOS-docs] Create page about rebuilding SRPMS and preparing RPM environment

[Filipe Brandenburger]

Hello,

As discussed on the centos-users list, I would like to create some
pages on the CentOS Wiki with instructions on how to set up your
environment to build RPMs and how to rebuild RPMs. This content today
exists here:
http://wiki.centos.org/HowTos/I_need_the_Kernel_Source#head-a8dae925eec15786df9f6f8c918eff16bf67be0d

I would suggest creating these two:

1) http://wiki.centos.org/HowTos/RebuildSRPM
-> what SRPMs are, how to download them, how to install them, how to
rebuild them
-> link to the other page on how to set up your rpm-build environment

2) http://wiki.centos.org/HowTos/SetupRpmBuildEnvironment
-> install "rpm-build" package with yum
-> set up ~/.rpmmacros
-> tips on packages that are usually needed when building rpms
(*-devel, gcc, make, etc.)

Once those pages are done, the page on "building the kernel" may refer
to that one for the generic instructions on how to set up rpm building
environment.

Thanks!
