[PATCH] maintainer-scripts: Adding GIT_CUSTOMREPO parameters to gcc_release script.

[Navid Rahimi via Gcc-patches]

Hi GCC community,

I need to have ability to point to custom repository in gcc_release script. 
This small patch 1) does add a parameter "-g" to add custom repository to 
gcc_release , 2) does add a line to download prerequisites before building GCC 
(download_prerequisites) which is not present in gcc_release right now.

I tested the script on x86_64 Linux. 

    Adding GIT_CUSTOMREPO parameters to gcc_release script.
            * maintainer-scripts/gcc_release


Best wishes,
Navid.
