Note that this is not a packager tutorial but a note based on information provided by David Walser to help QA testers perform local builds.   

First install the mgarepo and bm packages and create <before> and <after> directories.
See /etc/mgarepo.conf.
.....
## uncomment it in case you don't have an account in the Mageia build system:
#mirror = svn://svn.mageia.org/svn/packages/
.....
Uncomment that second line and it should use svn:// which is anonymous.

Before enabling updates testing, download the sources:
$ cd <before>
$ mgarepo co -d 5 <packagename>
Note the reference number which this returns in case you want to revert later on.
To do that you would use:
$ mgarepo co -d 5 -r <reference> <packagename>
To download the current updated sources, enable updates testing and:
$ cd ../<after>
$ mgarepo co -d 5 <packagename>
These commands will create a set of source directories in <before> and <after>.
$ ls <after>
BUILD    BUILDROOT  RPMS     SOURCES    SPECS    SRPMS    

SPECS contains <packagename>.spec, a text file containing all the build information.
It is here that you can change the compiler, add or modify compiler flags and any flags for the link-loader (ld).  Hopefully you will not need to do that.

Then to build the package:
$ bm -ls
Providing this is successful go on to
$ sudo urpmi SRPMS/<packagename>*.rpm
$ bm -l

The last command provides a commentary on the build which is echoed in SPECS/log.<packagename> and will tell you if the build fails.

This might be sufficient but if you also need to install the package for further tests do:
$ sudo rpm -Uvh --force RPMS/x86_64/*.rpm
Adjust that for i586 if needed.
