You need to make sure that when arm-linux-gnu-foo (or
arm-linux-gnueabi-foo) is called, your tools get called. Putting the
path to your tools binary dir on the front of the PATH will help here
(may be sufficient). If your compiler is called something different
then you probably want to make symlinks from the normal locations, so:
/usr/bin/arm-linux-gnu-gcc -> yourgcc
/usr/bin/arm-linux-gnu-as -> yourassembler etc
If you look at the structure of a standard emdebian toolchain it shows
how the binaries are installed on Debian, so you can use that to work
out what symlinks to make.
There are various other ways you can run at this but that's what I'd do.
Supplied compilers are usualy quite self-contained so substitution is
not too difficult.
