Tests Failing on x86_64_gnu

[nick]

Greetings,

I just build,configuring and ran the tests from the upstream gcc git repo like this:
mdkir odbjir
cd obdjir
$PWD/../gcc/configure  --prefix=$HOME/GCC-deve
make -j8
make bootstrap
make -k check

Those are the steps from the offical docs unless I am missing a step i.e. does
make install need to be done or not? Don't know if this a reported issue or not.

Cheers,

Nick
