I wouldn't use /etc/environment for this if I were you. Try /etc/profile
instead (remembering to 'export' variables you set), or a shell
initialization file in your home directory. See the bash(1) man page,
under "INVOCATION".

I've never seen anything look at $GCC.

Use CXX instead.

I doubt that will be used.

Figure out, possibly on a case-by-case basis at first, what environment
variable it looks at to find the compiler. Change that environment
variable. Make sure it's changed by typing 'echo $CC' at a shell prompt.
The Linux kernel's build process appears to look at $CC. I don't know
what you mean by "the 2.95.4 cpp-libs"; the kernel does not use C++ nor
indeed the system libraries.

/usr/share/doc/gcc-*/README.Debian.gz documents it briefly. Particular
environment variables are documented in fragmented ways throughout the
documentation for build tools like make and autoconf. In general people
who are changing compilers around are expected to be willing to look
through Makefiles briefly in order to figure out what to do: it's
usually near the top of a Makefile and easy to find.
