For what is worth, there are thousands of things that can fail when building 
GCC and it is very easy to make a mess out of it.

My advice is to follow the docs to the letter and script everything that you do 
so you can easily start from zero and do the steps again.

Start here: 
https://gcc.gnu.org/wiki/GettingStarted#Basics:_Contributing_to_GCC_in_10_easy_steps
Check also here: https://gcc.gnu.org/wiki/FAQ

My personal build+test script is here: 
https://gcc.gnu.org/wiki/ManuelL%C3%B3pezIb%C3%A1%C3%B1ez?action=AttachFile&do=view&target=gccfarming

It may be a bit outdated and it is designed for the GCC Compile Farm, but it 
may give you ideas for creating your own. If you are testing a fix, the most 
robust approach (and the one followed by my script) is to have a pristine copy 
of the source tree and a pristine build and, separately, a patched version of 
the source tree and a patched build.

I hope this helps,

Manuel.
